I am looking for both left and right side exhaust manifolds.
1966 Dynamic 88 425 single exhaust.

Thanks

sorry for not getting back to you on these i've been busy,i do believe you could and should find a better right side than i have.the driver
s side i have is decent.if you find someone with a pair grab them

Johndave

I am hoping to find a decent set.....but if I can't I will get back to you for the one f you will split the set.
Will the dual manifolds fit without any modifications...
I may have to change over to duals if I have to.

I just pulled them off a 66 98, need to give them a look and see condition. In NJ

384784 RH384785 LHBoth have a D on them.......
that is what I have and mine are both cracked right at the dump port on the bottom side.

I have this “T” 398708 which shows to be correct for 65-68, I may have faulty info seeing your numbers off the existing manifolds

That is the bad ones right there. They look close but not real sure.

jcdynamic88

casting numbers aside i've found 65-74 right side manifolds from a big block 88/98 interchange
