SWB Frame for LWB - SORRY! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

DriverDown · 07-08-2002, 11:35 AM

I know this has probably been beat to death by now, but I've gone through about 22 pages of this board and done several searches and couldn't find the information I was looking for. I'm fairly new to this board so may not be looking in the right place, so I apologize in advance if I should have found this myself...!

Anyway, I have a 69 C-10 LWB with a wood bed and found what I believe is a 71 SWB frame (with one door, one fender, and a small window cab still attached) and had some questions about swapping frames. Is it as simple as swapping frames and bedsides, using the parts I have on my truck (bed crossmembers, etc.) and ordering a SWB wood bed rather than a LWB bed (and saving some $$$) or am I fooling myself...?

Thanks!

Yes, it should be a direct swap, But you said the SWB had a small back glass? Then someone has put a 67' cab on it or it is a 67' SWB. Does it have disk front brakes? They were standard in 71'. But everything will line up to the mounts on the frame with no problems. I hope that this helps!!

The bed will not bolt up. It is too long between the headboard and wheelwell and between the wheelwell and tailgate.

No the bed sides will have to be Short wheel base.

Thanks guys -

I should have said swapping frames and SWB bedsides that I have yet to buy - either Goodmark or some good used ones at less than astronomical prices... I wasn't planning on trying to use my LWB bedsides(!).

Anyway, it may very well be a 67 with a 71 front clip on it - it had 6-lugs and drums all around if I remember correctly... springs in the back if that makes a difference...

Anything I should check out particularly carefully on the frame...?

Look for cracks around steering box check out the braces that's pretty much it. Yep if it has drums then I would say somebody put a 71' clip on it, The rear springs if they were coils then it's probably a Chevy frame, If they were Leafs then it's probably a GMC frame, But it doesn't matter either way!!

Thanks again!

I'll try to take another look at the frame today...
