F150 Regular Cab,Extended Cab Question.
 

I have a 99 F150 4x4 extended cab short bed.Will a fiberglass cap like a Leer,from a 99 F150 regular cab short bed work on my truck? I thought they were the same but have been told so many different things,that I need some help. To all that reply, Thank you very much.

Yep, as long as they are both flareside or styleside, whichever you have.

Both should have a 6.5' bed.
