Re-arching Leaf Spring question

I can vouch for McVeigh springs. Bought a set 5 years ago for my '71 off ebay. Got the added leaf version for an additional 3" lift. They gave me the exact rake I wanted, fit perfect & haven't dropped a bit in 5 years. When they arrived they were drop shipped from Philadelphia Spring(it appears McVeigh is only a middle man- BSW) only about 20 miles from my house. Idk if they were actually made in Philly, but it is quite possible.
They cost me about $230 with shipping. Included bushings. I'd buy them again.
