Tracker Throttle Body Base Gasket Question

[fixkick]

the bottom viewed one with long curved slot.
great question, the gasket with no slot is for AT  only car.
and fits below the A/T preheat device,
the one with the slot fits only directly below the TB base and is the vacuum ports. normal.

sadly no maker of this explains that, that ive seen

here it is working on 91 MT car, perfecly and home made by me.

I own punch set and exacto knife and do this in 5 minutes work using NAPA raw gasket paper sheets. (not bragging just showing how easy it is)

rule #2 the must be blocked holes.x5
