I've heard alot of good about these new venture tranny's .My 87 K5 has an SM465 and an NP208. Can I swap in a 92-94 NV4500 and bolt it up to my NP208? or would I need a a different T-case Too? Or is there an adapter for this conversion? What type t-case was typically found on the NV4500's. and we're they anygood?
