Throttle body gasket question...
My gasket kit came with both of these gaskets and if my memory serves me correctly when I took it apart there were two gaskets between the TB and the plenum. Am I supposed to install both of these??
Just want to make sure before I put her together, Thanks!

Re: Throttle body gasket question...
The bottom gasket is for early throttle bodies. The top gasket is for later throttle bodies. Use one or the other, not both.

IIRC, the top gasket is used with '88-'92 throttle bodies. The bottom gasket is used with '85-'87 throttle bodies.
