I am changing the single exhaust to dual exhaust, but I have a singel exhaust trans cross member. My question is what A-body years will work. I have heard that 73-76 would work, because these years did not have the cat conv. Any help would be great

 

You are correct. I believe, though, that the 73 was the only one with the double hump. I could be wrong, though.

 

Wasn't this covered in your last posting request??

 

Sorry just trying to get some clarification on if a 71 cross member would work. I didn't know you were the forum police.

 

I'M NOT SURE IF THE 71 WILL WORK OR NOT. yOU MIGHT TRY POSTING YOUR QUESTION ON rEALOLDSPOWER.COM, OR, OLDSPOWER.COM. tHERE ARE SOME REAL GOOD PEOPLE ON THOSE SIGHTS AS WELL.
dAG NAB IT, i HIT THE STUPID CAP LOCK BUTTON!

 

Forum Police?....Hmmm....Surely not I, but when information is given that I believe to be very accurate is not recognized or followed up with a comment or question, I have to wonder. Is it a cross over that you really need or was it the cross member? When you start making changes to a car that stray from stock there is nothing cast in stone. A lot is trial and error. If you won't believe information given on forums such as these why ask? To see if a 71 will fit take some measurements with a tape measure.

 

1973-1974 gm a body will fit 1975-1977 gm a body cars
