OK to answer cruzin one set I have is missing the mounting studs & I can slip the other set right in to them & everything is identical side to side top to bottom,there are 2 spring eye bolt mounting holes.
TommyD I see your hangers are for 64/70 Dodge B 3 1/4 & if SS springs are 2" shorter then stock springs my 5 1/4 hangers should be for a 66/70 Dodge B using SS springs,and I think I read Dodge factory springs are 1" longer then Plymouth springs then my 4 1/4 hangers should be for 66/70 Ply. B using SS springs.does this make sense.
