Mancini Extra Heavy Duty Rear leaf Springs

I bought Espo springs. They have 1" and 2" over I believe. I bought the stock ones for my 66. I mis ordered and got the 5 leaf and not the 6 like it was built with. Here's a photo after 10 years and some 235/70-15's on the rear.

Looks good. Maybe a good mistake in ordering. Smoother ride too.
