Crossmember Trouble..... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I ran into a problem while trying to put my sectioned crossmember in (from a 86 suburban), it is give or take a little a 1/2" narrower at the upper a-arm towers than the original (a 74 pickup) both half tons.
Did the frame width, maybe even the track width change at some point during the long production run of these trucks?
Or is there a difference between the suburban and pickup crossmembers that I wasn't aware of?

Will it be ok to go ahead and get this one on here, or should I just section the original?
