I'll have to look. I don't think I even have a car with the stock rear uprights. I think they are zero, but I can not be sure.

Sorry, will take some for you.

I just found another TZ on ebay for under $120. It is the rotary carb, no pull start version, but it was cheaper than a new piston/sleeve plus carb. It could fit in a TGR since I have a start box set up for 2 of those cars.
