i asked inline tube about the firewall grommet. they said it didnt come on the parking cable so i bought one, but when i got the parking cable kit it had one on there. i dont see why they even sell it because theres no way to put it on unless your assembling the whole cable from scratch
your parking brake will work if the dash is in the car and everything else is hooked up.
i got a couple handles i didnt use because the plastic handle was bent from years of people pulling on it. but i had a nice straight one in a parts car.
i also got my front fender bolt kit from that ebay seller. it was around $46
