I have been working on the engine and trans for my 56 dodge PU project. I'm close to having my 230/A833 OD setup ready to install. Next will be the change from floor mounted clutch/brake to hanging pedals from a 60 Dodge truck. I have the firewall reinforcement plate and pedals that were cut from the 60. I didn't do the cutting, nor did I see it before the cut. What I need are measurements to accurately locate the plate on the firewall. I think any 58 thru 60 dodge with a firewall mounted master cylinder should be the same. Here is a pic stolen from the web of the part I'll be installing.The vertical straps are not part of the project. They are for a power booster install. I have a firewall section cut out around that reinforcing plate with upturned edges I plan to separate the plate at the spot welds and attach it to my firewall with plug welds. I need to know the location of the master mounting holes on a 58-60 cab. I can install the pedal brackets and roughly locate the holes from the pivot points, but it would be nice to have the factory locations to confirm my guesses. Even a good pic of a 58-60 firewall big enough to show the master cyl and more of the surrounding area would help. the reason for the hanging pedal swap is due to a clutch housing swap. It is from a 58-60 truck also, with a RH clutch throwout lever, hyd operated. That also required the matching crossmember as the mounts are different. And the housing was a special unit only available for a few years. In case the 230 doesn't make me happy with horsepower, the housing will also bolt to early hemis and A series v8s. An LA also with a mod or two.
