Bucket seat info
Hi Hank,
You didn't say if you wanted to use stock 69-72 Chevrolet buckets or something aftermarket or new style (leather,electric, etc). 69-72 p/u trucks did have the option to order buckets instead of bench.You can use the buckets from a blazer but the passenger seat brackets had a fold-up hinge and releasing latch so that the rear of the truck could be accessed by passengers. Both blazer and stock p/u buckets and brackets can be purchased occasionally on ebay.
