cab swap

[Melavious]

I have a 1993 GMC Sierra K1500 extended cab. I am wanting to get a cab with the extra door and am wondering if the frame changed from 1998 to 1999 or if I would be able to put a newer cab on my existing frame.

99 1500's are a different style frame their the new body style

The 99 classic is an OBS.
