It's around 70.5". Get a couple from the parts store and take back the ones that don't fit.

Best bet. Take a measuring tape and run it around the pullies as if it were the belt. Then you can get can exact size without buying several.

ya ya . the other guy said he had the same mod and that worked
anyway why do you say 70.5 ?? i ask because as you know every inch make a big diff./ so i dont want to go to small. 73.5 the idler pulls it tight but it hits the belt oin over the water pump
i am thinking 71.5 but if you are sayin you know. then i will get the 70.5 .. i know these belts stretch alot after running them

You simply have to either measure or trial and error it. For example, my car with the 3g alt uses a 74.5" belt that fits perfectly. The 86 GT will have a different size waterpump pulley than 87+ so that will throw it off right there. Somewhere between 70-75 inches will be what you need, you'll have to figure it out for the exact measurement.
