elongating holes on shock plates

send it to a machine shop or a freind with a mill. thats some heavy duty stuff to just grind thru... unless u torch the holes and then clean them with a grinder....

You would be amazed at how fast you can elongate the holes with the plate in a vise and a simple rat tail file.

Having said that, I would just get a set of 8.75" rear shock mounting plates!!
