I want to run 3 point "normal" lap/shoulder modern retractable style seat belts, does any one know of a good place to get belts? Preferably something with little to no plastic..
Look on line at the following link; http://www.seatbeltplanet.com/. This is the internet store front from Beams who makes most of the belts sold by aftermarket companies. I bought them for my '50 Ford (two 3-point and four lap belts) and the total cost was less than the quote from another supplier for just the 3-point setup.
I run seat belts in all my cars. I install them to NHRA specs. If through the floor a minimum 4 inch square washer under the floor and minimum 7/16 bolt.
us bikers have a saying...if you have a five dollar head go ahead and get the five dollar helmet. Whats your/sons/daughter/grand kids life worth? time to spend a little money.
