I'm another guy that's been enjoying your site but haven't introduced myself. Hi, Mark from WA. I was a kid when these trucks were new and always wanted one. After years of building Chevy sedan street rods, our 1960 GMC was purchased from the nephew of the original owner back in the early 90's. It was essentially dead stock and well cared for. I enjoy restored vehicles, but prefer hot rods myself. As a result our 60 now has a 350/T10 4 speed and Dana 44 rear with 4.10's, front disc brakes, power steering, etc. I'm semi-retired now which provides more time for tinkering. I recently did the upholstery and some cosmetic engine improvements. I'll post some pics in the Members Trucks shortly. Thanks for a great site!

When I originally built the truck I switched from the granny 4 speed to a 350/350 automatic. After I swapped in the 78 front suspension/disc brakes I also installed the Master Power Brakes booster and firewall plate. About 5 years ago I switched back to a manual 4 speed and purchased the Master Power Brakes clutch cylinder bracket, which is set up to use a Tilton master cylinder on the driver side of the brake booster. A picture is shown at www.mpbrakes.com/products/product-detail.cfm?product_id=190. This arrangement put the clutch master cylinder directly in front of the pedal arm. My experience was this was a faulty design and didn't function well, flexing during operation. As a result, I pulled the new parts and engineered my own design. I fabricated a larger firewall plate for support and mounted a Girling 3/4" master cylinder directly in front of the original clutch operating arm, which is to the right of the brake pedal on the far end of the pivot shaft. I've included a couple of photos to clarify the installation and shape of the firewall plate. The Girling master cylinder can be seen at www.lreracing.com/girling_master_cylinders_and_kit.htm. For the slave cylinder I purchased a Novak kit designed to install a Chevy V8 in a Jeep www.novak-adapt.com/catalog/kit_hcrc.htm. It's a little spendy but it works perfectly. If I can help further let me know. Regards.  ,  |

One last thought looking at the clutch rod pic, I used heavy wall steel spacers between the operating arm and the heim joint connected with a grade 8 bolt. This allows the pushrod to be in perfect alignment with the master cylinder. I double nutted the bolt so I could set the tension and insure it couldn't loosen.

It's been a number of years so I don't remember all the specifics, but the bracket mounting the clutch master cylinder moved around every time the pedal was depressed. It just didn't seem strong enough to me. I also had problems with the pushrod-pedal connection. I remember I kept adjusting washers and spacers to get everything aligned properly and was never happy with the installation. I seem to remember the MPB bracket also put the master cylinder so close to the booster it was very difficult to get the lid off. It is possible to use a remote reservoir, but it just seemed like too much trouble.
The bracket has served well however as a bungee cord connecter for the brooms on my garage wall! Good luck on your installation maybe you'll have better results. Regards, Mark.
