Ok, sorry I haven't responded sooner. Working on this exhaust is so exhausting. Pardon the pun. I have some pics of the manifolds installed. The manifold numbers are 53010187. and 53010188. They are supposed to be from a 2002 Dakota RT magnum engine with rear dump, but I think they were available for a few more years. They WILL fit in a 1965 A body with mods to the passenger side. The drivers side will require the Flaming River Mopar conversion shaft, and a manual steering gear box. The flow is comparable to headers. I actually fired it up, and power braked it in my garage. I put it in drive, and let it shift automatically. It went through 1, 2, 3, clear up to 6000 rpm and it wouldn't stop until I let off the throttle!! Everything is very tight, but it is possible.
