Questions: Does it matter what way the transmission mount is installed? It has a nub on one side, not sure if that goes towards the front or the rear.

Questions: Regarding transmission mount, I have steel adapter plate, but it is still not matching up, the 4 holes are off by .25 to .5", any advice? Is it just a matter of trying to tweak/shift the trans a bit until holes match up? Thx

Questions: There's a bolt attached adjacent to the rectangle mount on the crossmember. It seems to secure a bracket to the frame that also has a tooth adjacent to the bolt hole. It seemed mine had a wire wrapped around and extending to the rear (of course cut off from destination). Is this some type of ground wire? It doesn't seem to be an add-on, because of the 2 holes in the crossmember.

Questions: gotta dana 18 and one of the side mount ears is broke off the casing. what do you recommend?? cant really afford a whole new housing.
Question By: derek on Dec 15 2017 6:49 AM
You could try to JB weld it if its not too bad. But really getting a new housing is probably your only option.

Questions: The transfer case label on my 47 CJ-2A identifies Spicer as the manufacturer and also as a Brown Lipe gearbox. Spicer serial # is J 121754 and it is stamped Model 18.Is this the same as the Dana? The transmission is stamped T80 - 148. Is the 638629K what I need?
Question By: Ed on May 21 2015 12:00 AM
Yes, that is the Spicer Dana 18 transfercase. Your transmission is a T-90. Yes, this will be the correct kit for your Willys.

Questions: I'm replacing the transfer case rubber mounts on a 45 Willys and we have the old bolt out and the small lower rubber snubber off. But, the problem now is getting the old large, upper rubber snubber out. The transfer case is resting on the upper snubber. Is it possible to remove the old and install the new snubber with the transfer case resting on the upper mount? Or is there much more to it? Thanks
Question By: Anonymous on Jan 3 2013 12:00 AM
I would drop the transmission and transfercase down and unbolt it all together to install on the crossmemmber.
