I would like to know what GM A-Body models came with the following rear shocks. Also, were any of them considered "heavy duty".

3192823
3186919
3197636

I did locate some information that 3197636 might be a H.D. Shock used on 64-67 Chevelles, including SS's. Is this information correct?

Appreciate any input gang.

Don..These numbers are from the 1970 P&A 30 A book
3192823= Rear, 68 chevelle( exc.sta wag, SS, H.D. susp, Air booster.
3186919=no listing
3197636= Rear,67, Pass,(exc427, sta wag,taxi,HD chassis,HD susp, Air Booster,SS)
Thats a lot of typing for me.

Thanks for the info Tony graemlins/thumbsup.gif
