Here is a pic of the cap with the drilled opening for the vent tube fitting ( I have that too).
I have not assembled it yet but was concerned that it would leak. The thread look kind of scary.
Besides that, the main question I was asking was, where there any issues with the company around the time the quite was built?
Should there be things I look for when assembling the car, like poor fitment of fiberglass pieces that will need alot of work or poor gelcoating?
