Front leafs
Guys, are the front springs on F100s '61-'64 interchangable? Got a tired left front that should be replaced and have a chance to get one from a '61. I can't measure the donor due to distance constraints, but I'm assuming the GVW is the same for all with a V8 in them.

from all my aftermarket catologs, they should be the same. the only thing that would be a problem is what the weight rating on the 61 spring and the 64 spring is. If the spring from the 61 is the same number of leafs as the 64's that your replacing, i would think there would not be a problem in swapping them.

Just because the spring has the same number of leaves, it doesn't mean it's the same spring.
The H/D spring leafs are thicker than the standard spring leafs, so the load rate is different...as you can see:
C1TZ-5310-C / marked: C1TT-5310-AL / 6 leaf / 1000 lb. load rate
C1TZ-5310-B / marked: C1TT-5310-AN / 6 leaf / 1100 lb. load rate
C1TZ-5310-A / marked: C1TT-5310-AM / 7 leaf / 1200 lb. load rate
The marked number is on the main leaf, near the eyebolt.

There are two types of main leafs for 61 to 64. They will interchange side to side.
The large rear bushed.
The small rear bushed.
And i assume the parts numbers would differ.
Don't care what the parts books say, you need to have a matched pair with the correct rear bushing ends. These are well used, and the odds of finding the part number still stenciled in or on them with yellow paint is nil. And they can only fixed by re arching or replaced by having a spring specialist make new ones, or purchase a old one that may be clapped out also.
If its sagging take both to the local big truck spring shop and have them re arched and re bushed. Should run less than 250 to do the entire job.

With the correct ID numbers, matching the springs can be accomplished.
I'd like to see you try and find what those ID numbers refer to without the parts books!

if it was 1964 i agree Bill, but its fourty some years later and unless the ford part is pristine NOS with the stencil number in place the part number is long gone... So side by side they look the same other than the large bushing in one and small bushing in the other,
Unfortunately in the real world the part numbers are long gone. An no one in their right mind would pay for a NOS leaf pack......

The ID number is STAMPED into the main leaf.
The stamp number is rather smallish...about 1/4" high...so it's not easy to see, 'specially after 40 years, with rust and other crud tossed in for chits and giggles.
