So im buying a 1981 chevy longbed and it currently looks to have a th350 bolted to an np208 t-case. I am going to convert it to an sm465 np... t-case. Now i would like to know from yalls experience, what transfer case should i be looking for? Should i look for an sm465 np208 combo or 205? which would be easier and require less modification? Either way im going to an sm465 so no worries about clutch pedal and stuff; ive got all that down. Or would it be a better idea to just change out the input shaft on my np208 to the 32 spline and just grab the 4 wheel drive tranny? Also, what about mounting? Is there a t-case cross member for the 208? if not is there a way to mount the 465 onto the th350 cross member? Any help is appreciated.
