Frame swap question

I am wondering if anyone knows if there is difference between a 74 and 77 Bronco frame other than the age?

I inherited a spotless 74 frame with a fiberglass tub that I bought and am considering putting it under my 77 Bronco if it will fit. Ideas?

Trac bar bracket is the only differance. might need a early type trac bar(pre76) to use the 74 frame.

Frame tracbar mount maybe slightly different.
Also VIN may be on a different location on the framerail.

'77 also has a different main fuel tank strap.
Fuel filler neck is different on the '77 (shorter and hidden uner fuel doors)

Maybe a few odds and ends for a charcoal canister and the like.

Thanks, it sounds like a couple of little things but the advantage of being able to drive my Bronco while I prep a second frame sounds really good to me. I have the title for both frames so that should not be an issue. Thanks again.

you probably already know this, but if you register it as a 74 when your done, in Ca. you dont have to smog it anymore.
