69 COPO "Recreation"

Shifters were the same but the engine mounts, trans crossmember, shifter mounting brackets and shift rods and lower lockout rod are different between big and small blocks. GM engineers had to offset the big block engine/transmission assembly an inch or so towards the passenger side for steering box clearance so that required a thicker shifter mount bracket to maintain its position relative to the console.

I've been told the bb shifter used a special oval shaped nut on the adjustment bolt, while the sb used a standard nut. In fact, a special nut sold on ebay a couple of weeks ago for $68. If it's true that they are different, can anyone explain why?

Check out my original shifter and BB bracket. You can see that my car has the squared off small block nut instead of the "oval" shaped nut. I guess nothing was perfect on the assembly line in those days.
