Default Intake Airbox Question

My 90 ZR-1 is in need of a new airbox--the part that contains the air filter.
I'd like to keep this thing stock, so I guess I'll have to find a used one.
The parts book shows two numbers: 13553505 and 14104555, but neither one seems available any longer. As for used, I think I heard at Carlisle this year that all of these airboxes are the same--the one from a regular '90 Corvette will fit the ZR-1 just fine. Is this true? There are several available on eBay right now, so please advise if you can. Thanks.

I have a complete rad shroud and a modded open back air box. PM me if interested.

I believe that only the 92-96 boxes will fit, as the 90-91 base C4 used a much smaller airbox. There will also be a nipple on the LH side of the air box which will require a bypass cap from the auto parts store. Not a big deal unless you're going for exact factory appearance.

The ZR-1 airbox and shroud is essentially the same for all years, as far as I know. The only airbox to avoid is the 90-91 L98 (base C4).

This is correct.
