There is a real skill involved in doing this work, even with the reproduction covers. It's different than spinning bolts or sanding rust. I dripped sweat over the work crimping hog rings using the better of the Ames pliars. It was finally partly installed with some error front to back, so it all had to come back off for a start over. This is one job where dropping it off by an experienced shop might be worthwhile for nice results. Mine is still sitting there all taken apart. I can't part with the money without another try with the fight. Something about my make up says this can be done at home in my garage. But it will go there when the car get's closer to finished. Quote was $500 out the door. Have it done is my hunch. Value you time. I don't see you getting by with under six or eight hours on each seat for a first try. Spend your time at what you're best at. Maybe some OT where you work will get it done.
