I'm working on swapping my 97 over to LS1 brakes front and rear. I picked up all the used parts and started to get the front LS1 spindles ready for powder coating today when I noticed one of them looked different. I measured them in a few different manners with the same results. I would imagine many of these used spindles are bent but how much can be adjusted for when doing an alignment? There is a difference of 7/16 - 1/2 inch between the left and right spindle. I don't know which one is the good one, just that they are different.

Below are pics of the spindles with a straight aluminum bar clamped between the spindle wheel bearing mounting surface to measure from.

Measurement setup

 

The height between the upper and lower ball joints should be the same as on your 97 spindles, use them for reference measurements.

 

I though about that also, but they are still on the car. I was hoping to get all the LS1 parts ready before I removed the LT1 stuff so I could move the car if needed.

 

I've measured them similarly, just laying them flat on the shop floor, side by side. A difference is grossly obvious.

 

Ask Sam Strano. He probably knows and is usually helpful in these matters.
