Bolt in Harness Bar don't do it!!!

JRLegacy you should read this article and reconsider...

sorry about the ebay purchase. however, 4 or 5 point belts should never be used without a roll cage.

That article is similar to what I said with just more detail:

"In a newer car (import or domestic), safety wise, it is definitely not better than a factory set up.
For an old Mopar with lap belts only, it is not a terrible idea. It is an upgrade over the stock lap belts as it gives you a little more support/safety"
