Exhaust Manifold

The driver side exhaust manifold on my 71 Super-Bee is cracked. The casting number is 2951865 with a date code of '71. I purchased another driver side exhaust manifold with the same casting number but the casting date code of '69. Will it fit right?

I would think so.I did the same thing a while back but not that many months off.I would say yes.Take a few measurements first.

The '70-1 manifolds are the same regardless of the casting dates for the B&E body manifolds. I have several sets here dated from 7/26/69 - 6/11/71 and there are no differences that I can see

The only difference's i know of on the HP manifolds is angle of flange where it mates to pipes. Can't remember exactly which years were identical and which were different. Thet look exactly the same till you take a good look at angle of flange. I beleive 68 to 70 are the same and 71 to 74 are same. The change came between 70 and 71
