change ups

the holes are different probably because GM just changes things... talk to a front end shop... always go to an expert....even on the dumbest things...you know what they say about asking dumb questions...... lol..

From what I barely know, 68-72 are the only years that cross over with your 71. 489 is right, if you have to use the 74 arms, better check with a front end shop, the geometry may be different also..

subframe update

:: hello
There is a difference of close to 1" between a 71 upper contol arm mount and a 74 /75 on . Plus the arm pivot bolts are not the same diameter. I need a later model subframe to match the control arms . ughh
