What frame fits 2003 reg cab Tundra ???

Hi All,
Looking for info to replace a rotted frame on a reg cab 2003 tundra 4x4. Missed the recall. I am wondering if a frame from an extended cab w short box would work with minor modifications? Cant seem to find many reg cab donors. Any help from the community would be very much appreciated!!

 

Maybe if your reg cab is a long bed

 

All regular cabs are long beds. An access cab frame with the short bed will work as they are the same wheelbase. It shouldn't need any modifications.

 

Did they make an AC long bed? I've only seen the regular size bed on en

 

No they never did.

 

I can measure mine to see the body mount distances later today if that helps. While the frames are probably the same length they probably have different body mounting points.

 

Ya those measurements would be much appreciated. It isnt too much trouble to relocate the body mounts. It is a long bed, so it sound like I may be in luck. Thanks guys!
