I bought this car out of Livermore CA in 2018. It's a 6cyl GT Tribute built on a 73 4 cyl chassis with donor parts from a factory six. I know, wouldn't do that today most likely. It wasn't running at the time due to mostly sitting for years. After a refresh of the fuel system and carb rebuild (thanks Jack Morris) it fired right up. New brakes all around courtesy of PMB and new fuel system components from Tangerine Racing. Thanks vendors! A few drives and compression numbers seem excellent. 180-190 on all cylinders. I'm going to pull the motor now to do valve adjustment, belt change, etc.
While the motor is out I'm wondering about how best to prep to install the shoulder harnesses in a better way. You can see from the photos that there is one point through the rear firewall with no extra metal that holds the shoulder harnesses at this point. I'd prefer not to install a bar behind the seat on the cage due to wanting the seat to be able to go back as far as possible. I'll be mounting a Kirkey or OMP seat I already have. I'm 6-1 and pretty long legged. I'm thinking about welding plates to the rear firewall about the point you see the 3 plastic plugs currently and then put two eye bolts per side to mount the shoulder harnesses. The car will be used for some vintage race events and DE's. It was originally built for PCA solo events. Thoughts, advice, pics of your installs?

A bit of an update and check in. Comments and suggestions welcomed.
I have an older FIA certified OMP seat that I picked up with some other 911/912 race parts years ago. Our club won't check the seat certification and it's in good shape. I will need to get a sub belt hole installed which I can do or have a local upholsterer take care of. I'm 6' 1" so getting leg room was a premium and also getting it as low as possible was a consideration. I may in the end need to have a pro add a small hoop to the cage above my head. I'm well below the bar with no helmet on but may be within an inch or so with a helmet. After much fitting and cutting off the stock seat mount hinges I think I got a decent fit. Then to figure out how to get a solid mount. I read through several threads on it and settled on this design which will bolt to the boxed section of the floor with a steel bracket and set of shaped slats I cut and welded. I'll bolt the back of the seat through the floor. |
