Have a question about bed sides.....

[TxSqueeze]

Alright guys, I'm sort of a newb to this site. Been lurking around for awhile, but I just recently purchased a 71 GMC. Actually yesterday! It's seems like a nice platform for what I'm wanting to do. Has 72000 original miles, 402 BB, tubbed with a narrowed ford 9". The only thing I don't like is, it is a LWB. I don't really want to mess with finding another SWB, because this bed is already tubbed, and has the center section raised as well. What I'm wondering, is there any way I can just order the bedsides and just cut the bed floor on the front and back? If I can, where can I buy bedsides for pretty cheap. I don't mind if they are reproduction, I'm not taking this thing to Barrett Jackson. It will soon be setup for a DD, and I don't really want to spend extra just to say it has OEM parts!

Any help would be appreciated....

Thanks,
Austin
