My sister owns an 87 toyota vanogan thing... How in the hell do you puit a new dizzy cap on this thing?!
Also, I cant find the plug gap specs anywere.

The "Vanagon" was a Volkswagen model. Toyota had the Van. Is that what you're referring to? Mid-engined? Four-cylinder engine laying on its side?

I believe he is referring to 87 Toyota Vanwagon.
If this is so, there are 3 screws that hold the distributor cap on.
The gap for 87 toy van 2.2L is .43
