I was unable to find a rwd 5 speed near me for a full size l, but found a ton of s10 nv3500s, so that's what I'm thinking of using. I know that one from a 4.3 truck will bolt up to the small block, and it will require slight crossmember mods. What I am wondering is if anyone knows where the shifter will end up? Will it be right up to the seat or will I have enough room for a bench seat? Has anyone done this swap before?
