1991 GT is the car


1. What is the bolt size used to replace the bolts on the rear of the heads when removing the smog pump? After smog pump is removed where are the two vacume lines you have to plug up?

2. Anyone got two spare radiator mount bolts? Or know the size?

3. Anyone have a diagram of how you put the rear drums back together?

4. Are there any ECU upgrades for my car? Can it be reflashed like newer cars?


Thank you all in advance.
