If you'll notice the date on my post (# 16 above), it's dated 2016. As such I stopped selling the manifolds years ago. But to answer your question, there are FABO members who have used the late 60s 340 driver and the 96/97/98 Jeep Grand Cherokee passenger's manifold on '65 A bodies. But they had manual steering and had to make some steering shaft adjustments/modifications. I don't know if the 340 side will clear manual trans clutch linkages. I have even ground the casting numbers off of the Jeep manifold to create clearance for the passenger's side fender well for the early As. I have no idea if your exhaust pipes will fit up to the 340/360 manifolds, I would recommend 2 1/4" dual exhaust pipes to get the benefit of the larger exhaust manifolds, (don't know what you currently have in your car?). You should do a search on FABO, I'm sure you'll find numerous threads about using the 340/360 combo on an early A. Treblig
