89 Square (crew cab) or GMT400? I know those firewall plates are different. Not sure on rod length
Not sure to be honest. Got the one for the 87 and it’s way better gonna try it and see how it goes the rod lengths seem to be the same .
Anyone dual drilled a brake pedal to have both vacuum and hydroboost capabilities?
I was thinking of using a tabbed lock washer on a shoulder bolt to keep it from spinning and just swapping the bolt over to the other hole when I hydroboost swap much later if ever.

I didn't do it but have the thought that if I needed it I would.
At this point I think all mine are HB
