Would a hydraulic clutch pedal and master cylinder bracket go right into an 80s gas cab? I know the electrical bulkhead connector needs to be moved but are there any other obstacles? Thanks

 

Gotta drill the holes for the clutch master bracket too.

 

You need the bracket that the Hyd master cylinder locks into, it mounts up onto the steering column/pedal brackets, then drill the hole in the firewall and move the bulk head connector down and over a bit, and a bit smaller too.

 

Thanks. So the shaft location and size that the pedals pivot on is the same? Doesn’t sound like too bad of a job. When did gas trucks get hydraulic clutches?

 

Correct.
I think the hydraulic clutches started in 88...
