    My 85 CJ7 originally came with a 5 speed manual trans, it now has a T 176 4 speed, which I'm having rebuilt. The trans crossmember, AKA belly pan that came on my CJ is in rough condition and needs replaced. Although, it bolts to the frame rails, the trans mount holes didn't line up to the trans mount and the PO used a torch to open them up, It has to be the wrong year for my Jeep. I've looked at after-market trans mounts, but I've decided to go back original. I need to know what years will fit my Jeep without mods and where can I find a pan? Thanks!

    The TDK unit looks good and are probably worth the extra $$$, but now, I have a lead on a good, straight factory piece, just waiting for a price. I looked at the one on my CJ this morning and I believe it's right for the year. I don't know why, but the trans mount holes hit about an inch and a half past the factory holes, towards the rear of the plate. The PO elongated the holes with a torch, so it'd line up with the T-176 trans. I'll have to figure out the alignment issue, before I spend any $$$. Thanks!

    I talked with TDK and I'll be ordering their pan soon, also I pulled the trans / T case out tonight,what a greasy mess! I'm sending them both to the rebuilder next week, I'm sure there will be lots of issues inside to fix. ( the trans had water in the lube and has a lot of bearing noise.) I'm going to see if I can find some better/stronger yokes for the the T case, also need a new front driveshaft or have mine redone. I'll post results when I get the parts back. Update: the tag on the dana 300 reads- 5361332 309003-2, according to the Novak site it's a 1980 with the shorter rear case, the trans is probably a 1980 also.

    Thanks for the update. For updating the yokes, you can get the yokes that were used on the earlier CJs that used 5/16" u-bolts instead of those straps with the 1/4" bolts that the newer CJs use. I have them on my CJ on the diffs and the transfer case rear. I did not install one on the front of the transfer case as driveshaft removal would be to complicated. Although I have not really known of any problem from those current u-bolt straps that the later model CJs use. Another option that you can do is to get a 4:1 gearset for the transfer case. These can really slow your CJ down when crawling although it does add considerably more torque which can break things like axles if you mash down on the pedal. On my oem skid plate, I did remove that lower bump that the skid plate has to add move ground clearance. Although my T18 transmission allows that bump to be removed, I am not sure how much clearance your transmission has to remove that bump. Hopefully you have the upgraded axles that the aftermarket does have.

    Yeah, I'm going to go with something bigger than the 1/4 bolt/strap setup, I read somewhere that dana 20 yokes would fit. Axles are the next thing on my to do list, right after I get the clutch, transfer case and transmission done. I'm not the horse I used to be, so I plan on installing the transmission by itself and then the bolt on the T case.
