Our product's quality and usability are highly commended with many customers suggesting a perfect fit for the Ford 350 and Ford F100, 1968 model. Its performance has elicited positive reactions from buyers, praising its functionality especially for braking efficiency even with drums. The material quality appears superior with customers electing to re-purchase it over mounting their own kits, despite occasional fitment issues. The product evidently outshines competitors as it enhances safety and provides excellent performance.

Nice stuff. I'd buy again
Ok. Everything fit together well. Bolted on truck fine. BUT. Needed to maje a ne firewall plate with new, smalker center hole, in new location to alight Everything and use the provided seal. Had to cut 2.5 inches out of actuator rod as it was way to long as well. But all in all. Pretty slick kit

Not even close to fitting.
It doesn't even come close to fitting. With the brackets bolted on the firewall of my '64 F100, the booster studs are 2" from the holes on one side. I also had 2 pieces missing from my kit. The mounting brackets are worthless, I would have been better off making my own kit.

The kit comes with almost everything needed to directly bolt it on and go. You will need to buy adapter fittings to go from the master cylinder to your vehicles brake lines. You will also have to cut the sleeve that goes from the pedal to the booster so it will fit properly.

I never write reviews, but this kit was well put together, and even included the proper brackets for bolting to the firewall. It came with all the necessary plugs and fittings, and didn't require several trips to the parts store like everything else I've ever ordered in my life.

I installed this in my project truck. I'm a long way from getting my project on the road. My only negative is the rod that connects the booster to the brake pedal was too long, I was thus unable to use it, however I was able to come up with a clean solution with parts from my local hardware.

A great upgrade

Easy enough to install, it would have nice to have some some basic instructions, but easy enough to figure out. A very nice upgrade !
