Mark,

A harness bar is used only to maintain the proper angle as the shoulder straps exit the seat back. Many people bolt into the rear seatbelt hard points. They are extremely secure. You will have to check on the length of the shoulder straps to insure adequate length. I don't think there is usually a difference in price if you go with the long straps.

However, I must continue my mantra regarding 5 and 6 pt harnesses and roll bars:

If you wear a 5 or 6 pt harness without a roll bar over your hear, you will not be able to move laterally in the event of a rollover. Your head will become the highest thing in the car below a rapidly descending roof. You would stand a better chance of avoiding injury or worse with a 3 pt shoulder belt. I view harness bars as being just plain hazardous. I would trade the harness bar for a roll bar.
