Question about frame lengths...
Good morning group. This question pertains to a '77 F-250 2wd.
I'm curious...is there a difference in the frame length between an extended cab and a standard cab?
What I'd like to know is, can an extended cab be replaced with a standard cab?
Thanks for the help.
Jim

So the frame on an extended cab is 9 1/2 inches longer than a regular cab, right? Could I trim the excess as needed?
Thanks again for the input.

I am not for sure how much longer the frame is but i have owned both of them and when my reg cab set beside my cab and a half the whole truck was about a foot and a couple of inches longer. Yes you could fill the gap in but what is wrong with your reg cab frame if you need a 4 wheel drive chassis i have a highboy frame.

I looked at doing the exact opposite for a bit, but wound up finding a '76 F350 SC LWB. What I found while pondering this type swap:
Reg cab long bed frame is 133" (approx. wheel base numbers)
Reg cab short bed frame is 116" (or 117" ?)
Ext cab long bed frame is 155"
So the extended cab is 22" longer than the regular cab. For this series truck Ford only offered one style that was the appropriate length (approx. 140") for an ext cab short bed combo back then, the very rare Super Camper Special. It had the rear axle set back 7" I believe so these beds only fit this frame.
Without some frame modifications, swapping cab sizes just won't bolt on.
Good luck whichever route you take.

Thank you all for your help. As usual I get the best information from this site. Go Ford-trucks!
