Hello, new member
Customer I build motors for, gave me a decent 72 F100. has a good 302 and decent trans, body not bad. Minor rot here and there, but totally accessible and not requiring patches.
Basically going to make it perfect running for delivering my motors and towing restored cars back to owners, then later blast and paint it.
Issues now are the rear leafs are sagging, and wiper motor is out. Thats about the major things.
Seeing alot of suppliers omitting the 64-72 on their leaf spring availability lists? Is that a hard item to come by? All I want is a little stiffer than stock, due to the fact I may put 4 motors at a time in the bed.
Any info, always appreciated, good little truck, and free is always great.
The F250 springs are longer, and will not work on an F100.
F100 rear springs are 2 1/4" wide. Length: << 24" eyelet 28" >>
F250 rear springs are 2 1/4" wide, but the length is different: << 24" eyelet 32" >>
There were different leafs options available, from 5 thru 9
A couple of samples:
C5TZ-5560-N .. Rear Spring-6 Leaf
C5TZ-5560-D .. Rear Spring-9 Leaf
Why spend $$$ for new springs, have your old springs re-arced. Spring shops specialize in this service and can also provide new shackle bushings.
Go to a Ford dealer and get part numbers for these old trucks??
LOL Good luck!

Someone earlier today needed a gas tank float. The parts guy at his local dealership said he needed the customer to provide the basic part number (!!), because he couldn't find it in the parts catalog. Ford used the same float for 23 years. It's listed in dozens of parts catalogs = 1957 thru 1979 and the pinhead couldn't find it? BS...he never looked, he just shined on the customer.

and also only 2-3 springs are the same thickness, all the rest have different thickness to them.
and i prefer to have new springs than having them try to re-arch them. ive only spoken to a couple of shops about re-arching them and they said it is better to spend the extra money for new ones, since i found a place to get them. cheaper price than what they would charge.
but to each their own. considering with new springs, 1 year warranty, re-arched only 3 months.

A couple of thoughts occur to me here... one low-buck way is that you could take apart your spring pack and add a scrounged leaf or two in order to restore your ride height and stiffen 'er up a bit. Probably take a bit of experimentation to get it right, and you may need slightly longer u-bolts to make up for the added thickness of the spring pack. Another thought is that some later bumpside F250s had a helper-type overload spring which simply bolted on top of the spring pack and didn't come into play till you had a load in the bed and the helper springs would then contact the frame-mounted rubbing blocks. These were also available on some F100s as I understand it.
You could also add air springs, or old school air shocks or even aftermarket overload springs such as pictured below:

Hope this helps. See you around!
