I tried to look this up in my GM parts book and found out that the whole section on shocks is missing
. Here is a partial listing and it doesnt say which is front or rear:
3192477 - 1969 Base, F41, L35, L48, L78 and Z28 - coded PS and PW
3192826 - 1969 Base, F41, L34, L35, L48, L72, L78, L89 and Z28 - coded TG
3192831 - 1969 Base coded TM
3192832 - 1969 L34, L35, L72, L78, L89 coded TN
3192851 - 1969 w/F41, L34, L35, L72, L78, L89 and Z28 coded UN
I have a set of original NOS spirals and they are
3192814 for the fronts
3192813 for the rear
I have a SS 350 with multileafs.
I dont know if this is any help for you.
