OK, let's say I find a 4BT that I can afford. Would the Dodge bellhousing and NV4500 (or 3500) have any problems fitting in a K5? Also, would my np208 bolt up to the NV4500? This seems like the best way to go. I've found rebuilt 45's on E-Gay for around a grand and bells for less than $100, fitment would be my only concern. Any opinions? BTW, I have 2 sm465's, could they bolt to the dodge 4500 bell since GM and Dodge used the same tranny? Thanks.
