Olds 394 4 Barrel Intake ID

I need help to identify a 394 4 Barrel intake manifold. I took it off a 64 Jetstar 1. I cant find any information on it. casting number is 587503 with a D1 on it. I just want to make sure it's from a 64 Jetstar 1 before I install it.

Thanks,
Pat

 

I wouldn't think that Oldsmobile would make a special intake for a Jetstar . The Jetstar 1 was designed as an economical alternative to the Starfire, but came with the same 345 hp 394, as the Starfire, so I would think it would have the same intake. My 64 Starfire has intake # 382856. I just sold the intake off a 64 98 that had those same numbers. I have a 63 Super 88 that has intake # 587503, but I don't see a D1 on it.

 

So what your saying it is very possible for the Jetstar 1 that I removed it from could have came that way.
Thank you,
Pat
