When I go to put a V8 in a I6 truck I`m planning on mounting in V8 position.Do I just use the same(I6)towers?I never thought about this before.Are they the same?This is the first 6cyl.I`ve had.This is a`72 shortbed and I`m using my`71 CustomCamper/20 as the donor.I plan on using the Dana 60 and shortening the driveshaft.

I6 and SB V8 mounts are the same, but mount in different holes on the frame. BB mounts are different altogether. There is much discussion about this in other posts... but I believe the concensus is that you _can_ mount a SB in the I6 holes with the possibility of slight clearance issues on the distributor.

Thanks.I`m mounting in the right(V8)location.Since truck was a 3spd with 1pc driveshaft,I`ll use the longbed one to cut-down to the right length(2 1/2"+/-)Not going to "tub" it,but am using the D60(4.10)w/Mark Williams 5-lug outer stuff.

You'll need different engine towers - that's the piece that connects the engine mount to the frame. I8 and V8 are different. If you put your V8 in the I6 position I think you can use the same towers. But if you move the engine forward you need the V8 towers. Same motor mounts, just different towers. I got my V8 towers from a board member for about $5.
