1965 dart gt spring question

I'm not sure if they are or not, but if they are any recommendations? I'd like to keep some rake to it but it be nice to use the stock mounting locations
i'd suggest measuring them and ascertaining what you have first and seeing what you're working with.

from there you can make a more informed decision on what pieces you'll need for a desired outcome.

lots of companies sell stock HD springs, which seems to be the look you're after. espo is one that is very well regarded.
