8 3/4 ?'s

when i did mine, I left the front on the floor and put jackstands under the rear framerails....to get your checks and measurements, put the car back on the ground and bounce the suspension to settle it....
it'll be a tight squeeeze, but I was able to get my measurements with the car completely on the ground
(for the pinion measurement, i slid up under from the back of the car, and for the engine/tranny measurement, you can reach in from the side and use the starter motor, the engine oil pan rail, the water pump face, harmonic balancer face, to to get your measurement....

as far as the pins working for caltracs.....i don't know.....if caltracs use a 5/16 threaded section on the pin, they will work....I'll see if I can get hold of them and find out what the center pins are, and i can make them to fit their monoleafs if you prefer.....i'm thinking they're going to be the same, but i'll just have to use a shorter bolt

let me know if you are going to use monos, and which brand if you are, or stock type leafs.....i'll need to know how many leafs if you aren't using monos....

if you are using caltracs with your stock springs, they will work anyway, and I will just need to know the # of leafs you are using
