Re: how tall of blocks before new driveshaft
 

Does your 87 have the original transfer case or did someone put the 205 in it? Most 80s SM465 trucks have the NP208 chain case, unless it was a 1 ton.

That said, it matters.

I have an NP205 in a '77 with a 4" Rough Country kit and that really maxes out what the front shaft can handle.

The 465 and NP 205 is the shortest trans/transfer case combo in these trucks, resulting in a really short front shaft.

While 6" is possible, it is better achieved with a different case other than the 205 for the front shaft . . .
