Gen 1 4×4 on a gen 2 2.6 block

I have the 2.6 running and I ordered a webber kit I found a parts truck (at my mechanics place luckly) it's sitting on blocks and the motor is blown ( rod next to starter). 200 bucks is got good parts so I think I'm going to buy it ( doors at my local junk yard are 87$ a peace so just doors and hood pays for itself) it's has a 4x4 transmission I want to know if it will bolt up to my motor or if I'm better off finding a matching block and building a 3rd 4x4 truck separately .I want to build my current 2.6 into a 4x4 and lift and skid plate it I also have a crashed 2.0 that I want to cab swap back to usable ( no window drive door smashed in) so the parts truck has enough parts if everything interchangeable but if not I can always find a new block and make a project out f the 4x4 all by itself
