Does anyone know if 73-85 4wd Burb shocks will fit 67-72 Burbs? I want to put a higher performance shock like the on my burb but don't know if the fit is the same?

I put 73 and up Edelbrock IAS shocks on my GMC 3/4 ton and had to compress them slightly in the front and the back shocks had to have the bottom mounts widened slightly. The ride is very good but I do not wish to make any mods on the suburban.
