I am wondering what the difference in wheelbase dimensions are on a 1994 long bed vs short bed. Has anybody ever put a short bed on a long bed frame?

 

No such thing.
Long beds were only available from 79-88, and 89 on trucks are only short bed..
now, the short bed extended cab has the longer wheelbase, which might cause confusion.
If you try and put a single cab body on an extended cab wheelbase frame of that era, you'll be hard pressed to find a bed to match, without some body work.

 

There were long bed 4wd trucks until '91 or '92.

 

Pics or it didn't happen.

I stand corrected. 79-91, 94 wouldn't be long bed.

 

They were only produced as single cabs, though.

 

Well of course, that's a given.

 

To some of us

 

just for referance .. we http://toyotafiberglass.com make long bed sides for this year as well

also making a dually flare just for ˟˟˟˟˟s and g!ggles (you can see it in the vendor section)




.

 

so a 86 toyota bed will fit my 94 no matter what?
