Im doing my motor and bought a professional products SFI balancer with the spacer for the late model accesories, now i need longer bolts, i went and bought some 3/8 bolts 1 1/2" long coarse thread but they wont thread on...what size is it?? I put locktite on the small screws that hold the spacer so i cant take them off but it was aligned when i installed it
 
a standard 3/8 thread, 3/8-16 (16 threads per inch)

i bought the PP balancer. with the .950 spacer. with my SC i had to go through and extra pulley but i used a 3 inch bolt. could have been a little shorter. are you having problems with the bolt not fitting the threads in the balancer or not being long enough?

The bolt not fitting in the threads is my problem i think the length is going to be ok at 1 1/2"
