OK...making a HD F150 from my SCREW. The 3 local Ford parts counters, one who works well with me, all want exact part numbers for torsion bars.
What I want is to know, what part number will give me the STRONGEST, LARGEST, HIGHEST SPRING RATE torsion bar.
Apparently, they come in different spring rates for pkg A vs pkg B or snowplowing.
Can anyone help?
Any info at all is appreciated.
