shock plates

[Snake]

Ok about 25 years ago a 69 Dart I had,had a 7 1/4 rear end.I up graded to the 8 3/4 thing is all I did was buy new U bolts for around the tubes, squesed them together and went through the lower 7 1/4 shock plates,why is it that when changing from one to the outher that we need different shock plates.I got to get this car ready for spring or I am in the dog house.I missed all last year and the wife is geting ansey.

The diameter of the axles housings are different I think. Same thing with mine. I took shock plates from a small rear and tried to put them on an 8 3/4. No Bueno!! When I look at Mancinis shock plates it does not say what they are for. Hope you get it fixed right.

I had exactly the same problem and I just used a piece of 3/8" plate and grafted the exterior shock mount to the plate and drilled the new holes in the wider pattern. The cost of new plates was way too much.

Theres a fix,still I seam to remember only haveing to push the u bolts in to get them to fit.

The axle tubes are bigger on the 8.75". You can elongate the holes in the 7.25" plate and get them to fit properly.

They are larger on 8 3/4 and the 8 1/4 rear end . You need the shock plates off either to work right .
