i just grinded the head off the bolt that holds the springs together. was this a bad idea?
there is still a bolt in there but is got a slither of a head cus i grinded that part off

The head on a standard bolt will not be round like a centerbolt will be, normally a slight bit shorter too. Just use one out of another spring pack, if you have available, most centerbolts are only grade 2 material.

sorry im not following?

Did you grind the nut off or the cylinder shaped side of the bolt?

um
i grinded off the top of the bolt

oh oh i get it, um i cut it off so i could get the lowering blocks to line up, so i dont really want to put another one in, i need it to be out really

is it bolt that is in the center of the spring pack or a rivet that is holding clip on towards the ends of the spring?

You need a centerbolt, other wise it won't stay centered to the axle, your block should have a nub on one side and a dimple on the other for proper installation. centerbolt should fit inside the dimple side of the block.

yeah the dimple is to far forward. could i drill holes either side of the blocks and put bolts there, so it wont go forward, and wont go backwards??

the hole in the blocks should line up with the pin ... this lines up the diff under the car
