GBS don't provide any real build instructions for the kit, so we were working on the basis that you probably want to start in the middle of the car and work your way out. An obvious place to start seemed to be the pedal box, something nice and easy to ease us into the build.
Ooh, how wrong we were! The clutch master cylinder needs spacing out from the chassis bracket if you want to get any kind of pedal throw and the brake master cylinder is mounted such that the pushrod doesn't line up with the hole in the pedal.
Matt made a new brake pushrod in a smaller diameter to ease the issue of the master cylinder not lining up with the pedal
After some grinding of the hole in the chassis bracket to lift up the master cylinder, and trimming a bit off the master cylinder casting itself, the pedal box finally functions!
Aaand then a dry-fit of the pedal box lid reveals this... GBS did replace the lid with a blank one, it seemed nobody knew how they'd ended up supplying this ill-fitting version...
Another head-scratcher we came across was the clutch and brake reservoirs not really fitting. A search in the GBS Facebook group revealed this was a known issue with the reservoir fouling the bulkhead. Some creative solutions ranging from panel beating the bulkhead to fitting a remote reservoir were noted.
We went for a slightly simpler solution. Cutting the little locating lug off the reservoir and turning it 180 degrees meant it clears the bulkhead with ease. To solve the brake reservoir not fitting we simply spun it around in the master cylinder. Couple this with the blank canvas provided by the pedal box lid now not having any cut outs in it et-voila, a neat workaround for the poorly fitting clutch and brake master cylinders!
The pedal bushes and assemblies were fun
But then once the pedals were in, the fun ended...
