thanks...you think Lowe's or Home depot carries them? Would an autoparts store have them? stock bolts are 1-1/4, I need 1-1/2.

no - you will need to go to an ACE or something like that



what you won't find are shouldered bolts, so the belts won't swivel anymore - this may or may not create a problem - you will need to make sure that you place the angle just right, so that the belt is pulled on equally, and not from one edge

Will this work??

it's awfully long - i think that you will have too much sticking out, even after you bottom out the threads - i ran into the same problem with the hardware for the chassis brace

Sorry, this is the one 1-1/2"

Well, appears you can't install both the harness bar and the shoulder belt together. The angle mount for the harness bar pushes down on the seat belt mount and prevents it from swiveling.

yeah - that is a problem - if you try to space it out, the leverage applied makes the mounting point unsafe - the only way for them both to work is if you can get away without the swivel, which means you have to be exact when you tighten them down

Got the harness installed. In my local PCA, it is illegal to attach the harness directly to a harness bar, can only be used as a guide. I hooked the two shoulder belts to the lower rear seat belt points (see pic) and ran them over the harness bar. harness bar is attached to the two front upper seat belt points (used weltmeister bar). I hooked the lap belts to the regular side seat belt mounts. I hooked up the sub belts by drilling through the floor pan, using eye bolts. I located them about 2 inches forward of the side seat belt mounts and spread them about 4" apart. Used a 3 inch washer underneath to secure eye bolts to floor pan, loaded it up with silicon to keep it weather proof. Pretty easy job, minor hitch was that the left rear seat belt bolt was pretty long and I had some trouble getting it back in as there is a 1" spacer to go through before the bolt seats.



Fun weekend, took the door panel apart to fix my driver-side window, put this harness in and put the track tires on. Looking forward to the first track event of the season this coming Saturday/Sunday at NJ Motorsports Park on the Thunderbolt track!!!

i understand why they won't let you attach the belts to that harness bar, as it is way too skinny, but somebody needs to slap the steward and show him the belt rules - that would never pass race spec - the angle is way too steep - you can't have the belts drop back behind the seat by more than 30 degrees - the fact that it goes over the bar first does not change the load on the strap, and therefore is just as unsafe as if the belt went straight down - in fact, it is probably less safe

Are you talking about the drop from the harness bar down to the rear seats belt points? if that is too steep, where else can I mount it? I thought the guide bar makes it doable. If that is the case, what is the point of the guide bar?

the guide bar is useless - no bar to which belts can be attached or run over can be less than 1.5" diameter and .120" wall - one good shot on that bar, and it will bend like a noodle and allow you to hurtle forward - that's why they don't allow them anymore



from the back of the seat where the belts come through the slots, draw a line that drops down no more than 30 degrees - that is the maximum angle allowable - anything less can result in spinal compression in a collision - there is also a maximum length that part of the belt can be too, but i can't remember what it is right now



the only harness bar i know of that would be acceptable is the redline unit - it isn't a roll bar, contrary to what it says on the website, but it is a decent harness bar, and i think any steward would pass it as such - you can attach the belts directly to that - you could fab one up on your own, but you would need to follow the specs, which are pretty specific, and even provide for non-rotation



the other option is a brace like i have made - it also meets the standards for attachment, though it is a lot more involved than you are probably looking for - but you really don't want to be taking that in and out



on the subject of taking it in and out, seat belt bolts and seat mounting hardware are designed to be "one use" - they are not designed to be removed and reinstalled repeatedly - the threads are much higher tolerance than normal - doing so wears out the threads and reduces the ability to hold torque and thereby withstand a collision



so, whatever you do, leave it there
