    Newbie here!!! Can anyone tell me the physical difference between Fisher's 7125 mounts and the 7138. They list both as fitting obd GMs. The 7138 fits K2500 and Suburbans with 7200 GVWR and the 7125 for K2500 and Suburbans with 8600 GVWR, but how close are they to being the same thing? Any way to tell on an older unit? Thanks in advance! Gordon
