I have a 71 Z that I am setting up for high speed autocrossing. To be legal I need to have at least a 4 point safety harness (all I have are lap belts now). I want to be able to retain the original seats (at least for now) and not upgrade to a racing seat. Does anyone have any suggestions as to brands/types/ mounting of a legal safety harness using stock seats? In the future I may purchase a racing seat so I would like belts to be adaptable to this at a later date but just not at this time. I would consider installing a roll hoop if that would give me the belt mounting points I need. I trust that you experts have been there and done that and can guide me right! TIA

You can get some good information from Racer Wholesale in Georgia -- or call them at 800.397.7811. They guarantee the lowest prices and should be able to tell you the best harness to get that you could use with a stock seat.

The mounting kits for the lap belt screw into the stock holes where your OEM belts bolt. For the shoulder harness, you will probably have to drill some holes and use their backing plate mount to bolt them on. Be VERY careful at reading the directions when installing the shoulder harness. There are specific angles that you need to be aware of so you don't end up getting a compression injury to your spine in the case of an accident. You may need to fashion some type of mounting bar that goes behind the seat at the level of your shoulders.

Thanks for the tip. I will give them a call and go from there. I figure a roll hoop would allow me the higher mounting point for the shoulder belts. From what I understand this would still not cost me points as this is a safety mod rather than a performance mod not like the racing seat.

A roll hoop is the perfect way to go. Some only come with a diagonal bar. It may be best if you can buy one without a horizontal bar and have someone custom fab one in at the correct height with the seat installed and you sitting in it.
