I’m going to check them out for sure but I’m concerned about ride height and and spring rate. The one shop in winterpeg can build a new custom set. Know some guys that have used them. Never heard anything bad. Just starting to research this all info appreciated.
Don't know if they are still around but I have had Manitoba Auto Spring do re arching in the past, they did the ones on my 70 Dart, plus added 1 leaf, never had any problems. Also had Standard Spring do a set on a van for me as well as the Ventura.
