A question regarding the D18 I am disassembling for the 58 wagon. Its a small case, 1.25" intermediate shaft version with 3-5/32" locating bore on the 58 willys. Trying to get the front bearing cap off...I've removed the two shifter poppet balls and springs, but the interlock pin is still in the the cap - and I think that its supposed to stay there until the cap is completely removed. Anyway, something is not the letting the cap slide off of the long (2wd/4wd) shift rail, and I assume its something to do with the interlock pin hanging it up somehow. Is there a trick to this I missed? thanks!
