Hello.

Got a '68 Ford F-350 Regular Cab Dually Pickup. Seems like most people only have springs back to '73. Any ideas?

 

I see what you mean. I only found helpers. I would investigate a shop in your area that does just spring work. They might even know if any newer years are interchangable with yours. It's the bummer of having very old vehicles is finding parts. Good luck with your search..

 

If you check around, spring shops can and do make springs, arch them and even install them if you desire.

Truck spring shops do almost everything .you just need to tell them what you are looking for and most can recommend or make springs to suit.
