The QA1 GS507 shocks are 2" longer (compressed) than the MS301 shocks on my car - 9.63" vs 7.625". I'm somewhat shocked (excuse the pun) they would be that much longer, especially as we're both running Mustang II front ends. Mine is an original MII front end - is yours, or is it aftermarket?

The GS507 has a tie bar mount on the bottom, whereas mine uses a spherical bearing and 1/2" bolt that passes through holes in the LCA. Maybe that's a clue you're running a different suspension.
