You do know that the D16A1 in the 1st gen tegs were unique versions of the D16, and not like the D15/D16 single cams at all?
I ended up parting out the 2 1st gen tegs I had, shells got crushed. Rare to find one in decent condition these days, good luck
Also I have a passenger seat out of a 88 Civic in great condition, I'd take 5 bucks for it if you want it.
