Quarter and Sheet Panels Installation Advice

When welding on quarters think of how the factory did it- no nothing in terms of weight. No engine- no interior just a jig. You need to make your own jig type set up.

If you preload you are shooting fish in a barrel. The quarters are part of the unibody structure. If you have the frame rails supported solid and level and the car is level then you have a good base to Install what ever part you need. I typically when doing quarter on a shell- 4 jack stands under rear frame rails and two up front. I shim them so the rails are level and tight to the car - use wood slices to get it tight. Jack stands move a lot and hard to get perfect since the dogs are typically 1” apart. Over the years I’ve done Lot of quarters. And no issues. Prep is 90% of the work.
