In reality you're choosing more than just which seats to use, you're deciding the entire future direction of this truck build - restored or modified.

There are occasionally some original Suburban seat sets on Ebay, but they cost a fortune. Check out MNSmith's build thread - he fabricated his own set of very original looking Suburban seats.

Since my truck was an economy build I went the other route and used a cheap set of GM buckets.
