Hot mess, a 1967 CJ-5 restoration

Good catch TJ. We are going to say it is a model 20 if there is only one stick. The year for the switch was 1961 62 ish on the bigger J series vehicles. The CJ5's were switched in 1972. So the 20 transfer case was around for someone to swap it in. And of course you never know what Willys might have done since the 20 was in the plant and so were the 18's for a long time.

The single stick 18 was in the optional Buick powered CJ's starting in 1966 (not used with the T90 trans). So it could also be one of those, a rare model 18 to say the least.

It is also possible to combine parts between the 18 and the 20 and build a Hi-Performance model 18 so to speak. They both can be built into a single or dual stick configuration. The biggest difference in the 20 is the case. It is stronger. The 20 worked well in the 1 ton trucks.

David, the shims are there to set the proper preload for the output bearing. Spray each shim with "Permatex Hi-Tack". A very thin cote.
