Good Day Fox
I had Standen Spring in Calgary manufacture new "to spec." springs
for our 1960 Imperial Lebaron eight years ago.
They had the Chrysler specifications for our car, I asked if they could make them so the car stood just a bit higher to combat future sag. The result was a perfect stance and is good today.
The installed price was $1,100.00 so your pricing is very good.
Looking forward in someday seeing your beautiful truck.
Howie.
