73 RS 3 point harness, like this

[Rex1968s]

Hi All,

I’m trying to duplicate this look with the harness. At first, i thought it was a 4 point. After zooming in, i realized it’s actually a 3 point.

1) how comfortable are these since the rear attach isn’t on center.
2) which set would you buy to get close as possible to this as I have exhausted search for these MOMO corse harness.

Best,

Rex

The Repa race harness is the correct option for Pre-73 race cars. I have been selling these for over 10 years to board members throughout the world.

Genuine 73 RS gave a forward facing threaded belt mount on rear shelf. I’ve seen a few non RS with this too but certainly not universally there. Harnesses back in day used to be supplied with papers that specify angles that are acceptable. While I don’t know if these rear shelf mounts on RS meet current standards being a period factory fit threaded mount I expect it might give better angle alignment etc for a three point harness than in photo which seems to use the standard rear belt mounts.

Hi Steve,

What does forward facing mean in this case? Not following no.

What a load of mumbo jumbo Steve. For clarity Rex1968s....The factory cars mounted the harness on the rear parcel shelf, not as in your picture. End of facts.

some photos, sorry for the poor quality, I needed to zoom...fyi, first picture is an RS shelf factory mounting point, second is the shelf in my clone (which was measured to the RS specification).





They were mounted under the rear parcel shelf. Various people have made replicas, John from NZ (whom I am still trying to get in touch with) was one, though I think he is gonzo.

And agreed, Jimmy makes fantastic stuff! I am deeply indebted to his awesome parts.

Hi Steve,
looked and notice i do have 2 mounting points on the hat shelf, which probably give a better angle then the ones pictured? I’m going to explore that option as well.


Hi @Stretch: do you have a picture of a 3 point. 3 inch, done in red, shelf mounted?

Thanks

Rex

Hi Rex, I don't have a picture of a Red harness because the factory cars and most others used the Porsche Repa webbing which is Black. The Red option in your picture is aftermarket.

Thanks for posting that image Rick. That shows what I was referring to! Factory Rennsport chassis typically had that mounting.

One point I was making “certainly not universally there” means not all “regular” i.e. non- Rennsport 911 chassis got those extra mounts fitted through the rear parcel shelf by factory however some did - a relevant point. Perhaps where those are not fitted (or maybe owner haven’t realised it are present hidden under rear shelf trim) is why we see owners using the rear lap belt mount for harnesses — these are lower and also off-centre.

The construction and position of the mounting points including the angles formed are safety critical so they were specified in instructions supplied by the harness manufacturer .. for example this from a British company who in addition to Repa supplied harnesses to Porsche racing team back in the day :

Incorrect mounting including choices that create inappropriate angles can risk injury and even result in the seat breaking. Something that owners who have an installation similar to that in photo in first post which seems to use just one of each pair of mounts designed for a rear lap to secure the tail of a front harness might want to check doesn’t create ill-advised angles w.r.t. a driver and seat!


The OP having followed-up on my comments and Rick’s picture regarding mounts seems fortunate to have a 911 that has that forward facing rear shelf threaded-type already present. As I commented this rear shelf mount is “certainly not universally there” on early 911 — the relevant point to OP being some non-Rennsport chassis actually got these rear shelf mounts fitted by factory, but others didn’t get them. Hence people offering them to retrofit. Some that got these at factory aren’t Rennsport racing chassis so perhaps it was done only for some years but not others or maybe a regulation regarding mounts affecting some regions/countries only. Not sure of the reason or the pattern where found why beyond Rennsport chassis but these are “not universally there ” in period. Cost reason perhaps? Whatever the reason it can be very handy if it turns out they’re present and still sound but being under the shelf trim some owners might be unaware of them when looking to retrofit a three point harness pair .

The fact the OP Rex replied to me directly saying he was able to look for and find such mount based on my comment and Rick’s subsequent picture suggests that comments offered something practical he could consider to address the initial query —

Not “mumbo jumbo” but useful input to OP it seems .. rather begs the question why do other posters feel the need to make “snide disparaging ” remarks on ESR?

Hi Rick, Jimmy T also supplies these and he's on your doorstep. See link below. Regards .Dave
