Hi Joe . . .

I hate it when the hunt leads to bagging the wrong game. Done it a few times myself :-(

The port spacing on that intake suggests it's for a Chevrolet.

With the McGurk and Howard design one can fabricate elbows to replace the ones on the intake. The outer bits would have to cope with wider spacing found on the GMC.

In general the speed parts for GMC were made in less numbers then those destined for Chevrolet's. This typically leads to premium prices on the GMC stuff.

Have you approached the Ebayer about a partial refund given the mistaken ID?

regards,
