Mike,

I just bought a new pair of springs from you folks for my 62 Falcon.  I don't have a warranty because I have a stroker motor installed.  I installed the springs on my Falcon and noticed a decent amount of slop between my spring perch and the leaf spring center pin.  I took the axle back out of the car and measured the hole.  It was way bigger than the pin that came on my springs.  I'm not blaming you guys, there's a chance that the rear end in the car isn't stock.  Anyway, I know that it is very important for the spring and the rear end to be firmly mated together without movement...

Here's where I may have screwed up:

I went to my local supply house and got a new spring locating pin with the proper OD. to FIRMLY locate my rear end.  The problem was that it was 3/8" OD. where it goes through the spring and my stock pin was 5/16" OD.  Using my trusty Dewalt and a little bit of WD40 I punched out the holes in my springs to the desired 3/8" size.  With the new pins in place, my rear end set very firmly over the pins and everything went together nicely.

That's when a buddy of mine (into 4-wheeling) told me that I probably destroyed my springs from the heat caused by the drill.  I used a little WD40, but not a lot.  It did get hot, because it ruined the drill bit.  He told me that if the heat from the drill didn't cause the springs to break, the stress risers caused from drilling a hole would (he told me the stock holes are punched and drilling a hole creates a stress riser).  I spent $500 for these springs and if I ruined them before the vehicle has even been on the ground I'm going to be sick.  What are your thoughts?

 

Thanks - Corey
