[Spridgets] Spring Hangers

[Michael Rowe]

Are bought interior patches like the spring hanger patch and associated rear panel patch normally butted in or lapped?  

I am wondering about the effect on the allignment of the spring bracket, if any as my rear floor has already been doubled with some fairly heavy sheet on the inside, so an interior lap there could be as much as 1/4" high.  An exterior lap would not be so much off.
