my freind had 80 coupe deville with hydros 4 pumps 6 batteries hooked up 6 more for weight they were too little of cca , but anyways i broke the frame hopping it no reinforcement i ripped the a arm mount of the frame on 1 side , he did it to the otherside last fall . so he said lets put it in the gp ,luckily the guy he got the car from put a 85 monte ss 305 in it with a 350 turbo . the top hydraulic guy in the state of mn was over the other day and gave my freind some ideas on what to do and pick up some parts to reinforce and extend and said the caddy brakes would work and have more stopping power in the gp they are like 2-3 inches bigger than stock g body brakes but the bow out a little but thats what we need wait till the 1in extended a arms get put on. i pretty sure the car should be rolling and bouncing by fri. atleast i hope so theres a car show sat
