hydraulic clutch in A body
I should probably re-make the bulkhead at the bell-housing for mine. The pressure line is quite close to the exhaust, but with the silicone/fiberglass insulator tube on it I haven't noticed a change in feather point or any other heat related misbehavior.
My clutch pedal arrangement isn't much different from the pic posted above, including using an SRE on the end of the push-rod. It is welded to the pedal rather what appears to be bolted with a long spacer, but I doubt that makes much difference. If the PP were something more than stock I'd likely need to add a gusset or two, but its fine as-is.
