shock plate pads?

isolator pack spring setups suck for any type of performance setup. they are designed to make the car soft riding, and a bit squishy. they allow the rear to wind up on hard accelleration. i dont recommend them for a performance car.

that being said i dont think the isolator setups were ever offered on the A body car line, if you are trying to fit this axle in an A body you are going to have to move the spring perch mounting inboard to fit the A body leaf spring width anyways. you will have to cut off the old perches from the C body axle tube.

go to jegs or summit, and get a set of mopar performance spring perches for 3" axle tube. brand new they are $16.00 so that hardly breaks the bank. you will still need 3" ubolts, and spring / shock plates for 3" axle tube.

unless you are looking for a specific pinion angle id recommend setting the perches and the rear end at the stock pinion angle the same as the rear end is thats currently in the car. a set of caltracs will prevent spring wrap up under hard accelleration. some guys want an additional 1 to 2 degrees down to counteract spring wrap up. if you find you need this additional degree down it can be had later on with shims between the perches and the spring pack.

i have a set of 3" ubolts that are used but sandblasted clean and come with the factory locking nuts. i can sell you these for $15.00. plus the ride. i have a spare set of the MP perches, but im narrowing another C axle that i may keep or sell after its done, so i need these.

you will still have to hunt down a set of shock plates. 67 to 72 C body should have them, as well as 67 to 72 B body. hunt your boneyards you may get lucky.

i got mine off a 68 fury lll sedan. got lucky and somebody got the axle from it, and left the plates in the trunk of the car. score and i didnt even have to use my floor jack or get dirty at the junkyard that day.

good luck on your venture, if you want the U bolts, just PM me
