Swapping cases

Already had a post about this but didn't get the answer I was looking for... Right now I have a 1980 Dana 300 that needs to be replaced (I think), I know that it is the shorter version of the 300. My question is, will any year Dana 300 swap right in without other issues??? I also have the t176, 258, and a Tom woods rear cv shaft.

CJ 300s should be fairly common since they were used for several years, but seems there was a one year only when they first change to it. You could probably find a later one and swap the guts with maybe the exception of the output shaft. Can yours not be built?

I'm sure it can probably be rebuilt but I thought it would be alot cheaper if I just found a good used one... My problem is that the front yoke for the front driveshaft has a tremendous amount of slop and play in it. So I'm not sure if it's fixable or what? I have absolutely zero knowledge on rebuilding one myself

Could just be a bearing, the rest maybe fine, these things are suppose to be pretty tough. Manual/transfer cases are not that hard to build, basic mechanical operation with a few special disassembly/reassembly procedures in some cases and few clearences to check. Get a book or google the rebuild and then jump in it, its broke now so you really cant do anymore damage and you will learn something even if you never reassemble it. Just a thought.
