Suburban cab for pickup

[19steve53]

Hello. I have a 1985 k25 that has the typical rust in the rockers, cab corners and firewall. I found a very nice 1991 suburban that is parted out to a bare shell that I would like to use to fix the 85. Has anyone heard of using the front section of a suburban cab to replace a single cab? I think that removing the rear of my cab to the A pillar at some point and grafting it onto the suburban cab. Seems that this would save a lot of time replacing the individual parts that need to be replaced. Thanks for any advice/responses.
