Sooooo I was able to get shorter belts, but they are a little too short. Issue is that alternator no longer drops low enough for me to get these smaller belts on (hits the top of the engine). I managed to squeeze one belt on, so I'm running with the one currently. Going to look for belts 0.5" longer and try those.
The car runs, but needs some attention after sitting for so long. Pulls hard up to 100 then starts to falls off (this is due to the previous tune). Also, ignition timing may be off a bit.
Front tires have done their time. Rear still looks good.
