91 Firebird 3.1 egr

Wondering if anyone might have the adapter plate that goes between the exhaust manifold and the egr for a 91 3.1 that they would like to sell.mine is cracked 1n 3 pieces,so for now i made a block off plate. I suppose I could just leave it like that(its emisions exempt)... But I would like to fix it right....Dealer wants $439 for the whole egr set up. 239 for the plate.And no junk yards have any 3.1s in the area.Any ideas? . And btw this is by far the best site in my book

90-92s had a digital EGR, the computer looks for it so blocking it off doesn't help. You pretty much have to fix it.

ive got one if you can find out how to get it where you are. I haven't cleaned it, but if you look at my past thread about my egr experience you'll see that all you have to do is take one apart and carb clean the $h1t outta it.

Thats what I did to mine and it never threw codes and I went from like 12mpg to 27! i got 27 two tanks in a row and it ran soooo much better. If you could figure out the method to get it, you can have it for whatever you think its worth.

just name a price.
