1980 750twin chassis measurement needed

After some unforeseen compromises were dealt with in making a custom swing arm for my 1980 twin, the bike is sitting much higher in the rear than i would like. I am evaluating my geometry because I either need a smaller rear wheel or shorter shocks.

Can someone with a 1980 KZ750 twin LTD give me a measurement from their rear axle to the upper shock mount? I need the stock numbers as a baseline. Also I would need to know the axle position in the adjuster. THANKS!!

sorry, mine is a '79.

Mine is a 78.

83 here. We're circling the wagons. :lol:

I still have the original swing arm somewhere in storage. Worst comes to worst I'll dig it out
