The brake pedal rod. Did you have to make one or did the one from the 2004 3500 box van work.

Thanks
I used my 3/4 ton MC. You use the mounting plate on the hydro boost to mount it to the firewall. You will have to drill some holes and mb weld some holes up. The brake pedal rod I just modified by cutting the eye off of the hydro boost rod then used the end of the rod off the vacuum booster and welded it together. Some guys weld a piece to the brake pedal itself the redrill the hole as well. Do a search on here and there are a couple threads that go into greater detail than what I did for this conversion.
