1970 Trans Am RA III manifolds
 

Hi, can someone guide me to the best replacement RA III exhaust manifolds for my 1970 Trans Am? My factory manifolds are casting numbers 478140 Left and 9799720 Right. One has a 2-bolt flange and the other jas a 3-bolt flange. I was looking to buy a pair from RARE, but all they seem to show for 2nd gen F-Body, say they require two 3-bolt flanges. I want a set that is direct fit, so I dont have to alter the exhaust flanges. I see The Parts Place shows a pair that has one 2-bolt and one 3-bolt, but everyone says RARE are the best manifolds. I also assume that all reproduction manifolds will have the wrong casting numbers on them for my firebird, as I have never seen reproductions that have my casting numbers. Can someone help?

Thanks

Call RARE and talk to Paul I would bet he has them unless they have had supplier issues.

Thanks Skip, I sent Paul an Email. I appreciate the help

Well.... Just an update, I gave Paul at RARE a call, and he doesnt make a drop in pair of manifolds that use a 2-bolt flange on the driver side and 3-bolt flange on the passenger side, both of his require a 3-bolt flange. We didnt want to alter the exhaust flanges, so we ended up ordering a new pair from Classic Industries last night. They are the correct 2-bolt/3-bolt arrangement, and says they are Made in the USA. They may not be quite as nice as the RARE manifolds, but they will work fine for what we are doing, and atleast they are not the Imported manifolds. I got the for 20% off as well with a promo code. Anyone have any experience with the USA Made manifolds that Classic Industreis sell?
