in the master link that is the right rod but wrong adaptor plate

you dont need and adaptor plate..you need a plate to renforce the firewall so it wont rip thur the thin wall when stomping on the brakes

I even bumped my 4 bolts up to 1/2 and used 2 allen head bolts and lock nuts for the mc

should be able to use the 4 holes that the booster used and just drill the 2 for the mc
