Will a 69 body bolt onto a 74 frame?

[Bleach]

I have a good line on a 74 rolling chassis that already has an engine on it and is ready to go. Will my 69 body bolt onto it with no problems? I realize this may be wishful thinking, not sure though.

Also, I am still in need of the metal bed floor to fit my 69. If I took a LWB bed floor, could I cut off some of the excess to fit my SWB. I know that the bed floors from 67-88 are pretty much interchangeable with the exception of a few holes, but I'd love to know if this will work.

Thanks all,

Tom
