Slick 60's

hey guys.i got a couple of questions about the frames and springs on the 53-56 and 61-66 f100s. Are the frame rails in pretty much the same location as far as frame widths??? are the leaf springs on the rear the same lengths??? The reason i am asking is I am looking at air ride technologies for air ride on my 64 f100 and they only make a air ride kit for the 53-56 and then the newer ford pickups and i want to know if i can use the kit for the 53-56 with lil modification.

Actually I believe 53 -56 frames are the same.
F Series 57 - 64 frames are virtually the same.
65 thru 79 are similar with 73-up having a wider CA & slightly different lengths.
So my short answer, from my PoV is No you can not.

To begin with there are no 9" rear ends until the 57 & up, Springs are different sizes & widths both by year &
model and there are other Subtle Differences. Having said that, I'll next say, with enough time & "cubic" money
anything's possible, but adapting aftermarket set ups to unlisted models, or series vehicles, will not be a drop in
bolt up deal by any stretch or means. Altho it's all different & may possibly be done, be aware it may just become
an expensive cobble job in the process.

I think that if it was a relatively simple, adaptable, conversion the aftermarket Mfgr would say so.
I mean, afterall, they are in business to sell what they manufacture, but they want to keep lawyers
out if as much as possible too.

ok. thats what i thought but i thought i'd still ask.
