I made my own bracket using 1/2" plate welded up and a box out of a late 60s Buick car.

I like it so far. Doing something similar, I put a used CJ2A fiberglass body on a 71 CJ5 with V6 and T14 transmission frame.

I'll post some pics of the T-18 later today, when I head out to the barn. Its kinda rusty from sitting bare clean all winter. Like all projects, it got put on a shelf for the winter, which has been kicking my butt. Way too much cold and snow this winter. But I have plans to get the frame over to the blaster next week. Then into the barn to begin putting the frame together and mounting driveline.

If your going to have the frame all apart and blast it that would be the PERFECT time to fully box the frame.

Metcalf, that is the plan, with power steering, dual master cylinder (when I figure out which one) the T-18 in the pictures and one of my dauntless motors. Trying to find out if I can use the original bell housing from my 66-V6, instead of adapters or new bell housing. This T-18, is supposed to be out of a 79 vintage V8. Not sure if it is or not, but if you guys can help me out, that would be great. It looks to be configured for the transfer case and have the right output gear already. the bell housing that came with it, looks to be a 304 bell housing. What do you think. Reverse is up forward and right in the shift pattern and the ratio appears to be in the right area when spinning the input shaft, a little over 6 to one. (632 ?)

If it's the CJ version of the T18 things get a little weird. That is pretty much exactly what I put in mine with a Buick 225. A few things to think about....

Your reverse is in a different location though so I wonder if it isn't an earlier version....

Make sure to measure the diameter of the splines at the input shaft.

-The input on the late CJ T18 is a little different than most. It is slightly longer. This means that the a stock GM bellhousing will NOT bolt up even if you could make the extra ears work. The depth of the bellhousing is wrong. What I ended up doing is buying this adapter from Novak.

http://www.novak-adapt.com/catalog/adapters/engine_to_transmission/kit_1879.htm

That adapter lets you use the stock buick bellhousing.

-You will need a new clutch disc. This version of the T18 has a 1.06" 10-spline input, not the more commong 1.125" version. Make sure you measure, I have seen some odd once. I used this clutch disc with the factory style buick 225 application pressure plate....

-The pilot bushing in the crank needs to be changed too. I think I found an AA part. I will have to look back in my notes.

-This transmission should have a factory texas pattern Dana 20 adapter and 6-spline output shaft. This adapter uses a 4" bore case, not the smaller more typical D18 version. I rebuilt a Dana 18 into a later model dana 20 case. They are basically the same thing, but you need the large 1.25" intermediate gear bearing kit and intermediate shaft. I use the dana 20 part since it was in very good shape and an oem quality part. The fill port will be different. The shift rail holes need caps on them.

There is also a custom spacer that fits between the transfer case output gear and the output shaft bearing on the transmission. I made a custom one. You might be able to find one somewhere?

-In order to get the Dana 18 twin stick front output housing to fit you will need to grind the T18 case to get it to fit ( and most likely the inside of the twin stick mount ).

That does NOT look like a Ford pattern T18 tranny, The Ford tranny has an extra set of 'ears' that are not drilled. Drilling these ears allows the tranny to be fitted to a BOP GM bell housing.

If it is the Jeep T18 you would need an adaptor at the front for the BOP bell housing, but it should bolt up to the large Hole D18 TC? I think this is consistent with what Metcalf described above.

He said is was a jeep CJ version.

I forgot to mention that I have the transfer case that came with this transmission. I also have a 4 inch transfer case on my 66 CJ5 donor. I think I should be ok with mating it up, just want to get my twin stick on there though. I have the complete drive line from the 66 donor, including the dauntless. The problem with the transfer case that came with this tranny is that its not an offset. But maybe I can use the bearing your talking about if its the right diameter.

The 4" donor case from the 66 CJ5 will work on the T18 Dana 20 adapter. That late model version of the dana 18 should have the 1.25 intermediate shaft. You will still need to do a little grinding to get the twin stick shifter to fit. You will also need to figure out something for the spacer behind the dana 18 input gear.

It sounds like you still have plenty of parts around to pull this off.

You will still need the bellhousing adapter with the Jeep T18 though to mate it to the buick bellhousing. You will also need the correct clutch disc.

Measured the input shaft length and its right around 7 1/2 inches, (roughly) The cast numbers on the top say its a 1977-78 year Jeep CJ version and the shift pattern confirms that. I was thinking of going with the Novak adapter kit that you mentioned or buying an advanced adapter bell housing instead. It will all make more sense, once I get the donor apart and can use that old frame as my template/running gear holder. I am also using the old motor mounts from it as well.

Does AA have a bellhousing that will go from the BOP pattern to the JEEP T-18? I thought all they had was a BOP/ford T18 version?

Your going to want to move the engine as forward as practical to give you a little more clearance on the firewall for the valve cover on the drivers side. It will also give you some more driveshaft length which will be important. Since your starting from scratch it is also the perfect time to think about raising everything up for more belly clearance under the chassis. Basically, don't be stuck on the stock motor mounts......

I was going to set up the drive line on the frame once I tack up the new body parts. Then change the angle of incident on the driveline. I was hoping to get the front of the motor up aprox. 1 1/2 and then angle down to the rear of the transfer case. I think I may be going up a total of 2 inch in front though. Then I can set the tranny/trans case mounts to align as needed. That should help with the angle of the rear driveshaft to rear dif. I was also going to try and incorporate the 1 inch body lift from my YJ. Figure I would slice them down on the bansaw to the desired thickness. I have a NIB kit I never used. I was hoping to get an inch lift on the body, when done. I got it, figured I use it.
