Hi Dan- Just so you know, the '64 is different than the '65-'66. I believe the casting number on the '64 ends in 306 and the later manifold ends in 316. The '65-'66 manifold is set-up differently for the kickdown brackets, as the st300 and the switch pitch was introduced in '65. Do some searching around using the board search function and I'm sure you'll find more info. :TU: Then again, judging from your cars and your site you may already know all of this.
might have what your looking for,I have a duel quad set up linkage, kick down switch it came off a 64 riv. but the numbers on this intake is b1357106L from my research thats a 64intake and the other one that I have is just the intake and the numbers on it is 1370316b and that is for a 65-66 in the process of resto on my66GSconv. not sure witch one to get rid of also have the air cleaner be hard to find one of those as nice as this one is, send a pm tell what you are thinking
Dan. I would not be willing to get rid of the 316 manifold as like you it is date coded for my car to as for the air cleaner I pulled it out of the box last night the chrome just as nice as I remember but looking at it on the back side of the cleaner there seems to be a semi-flat spot on it, and tonight I was looking at a 63 riv and where the hood comes down it looks like the semi-flat is factory to allow for some clearance,I have never seen another one to say if its factory or not but I will say this the chrome is perfect in that spot the area is uniform, not hammered ,to nice I would not want to let it go for under 500.00, I going to try craiglist here in Indiana then ebay, will more than likely put the other 2x4 on ebay also those things usually get 1500.00 to 2000.00 . sincerely GREG
