Cross-generation pedals/brackets compatibility

[Crabass]

Hey Sunny --- thanks for that info.
The setup that I want to end up with is the vacuum brake booster and hydraulic clutch. I have the complete bh/fork and all the hydraulic components and plumbing out of a mid '80's truck, bought 'em all together with a SM465 (IIRC) that I sold. I'm planning to use a car 5 speed with an adapter for the bh. Those 4500's are pretty rare and pricey, too, aren't they?

The parts truck seller emailed me a pic of the master cylinders area clearly showing the vac booster and clutch master. I'd post it here but there is no URL to post it with, and I don't have anything to do with that social media crap. One of the worst things to ever happen to our culture IMHO, but I digress.....

I was hoping that maybe the underlying structure of the later model cab would permit use or adaptation of the '89 hyd clutch pedal assy in my '87. One thing going for me is that I have available to me locally another same vintage truck with the setup I want, to inspect / measure / compare for fitment purposes. Looks like there is a lot of lower dash sheetmetal in the way of getting easy access though, and I won't be able to do any disassembly.

I'm interested to know what you need to get for a vac brake / hyd clutch pedal assy if you have that, provided it would include the linkages and fasteners required to complete the install. It would sure be nice to have that aspect of the project covered. Thanks again
