The chrome hydro replacement is big $$$.. I can get a chrome booster and m/c for reasonable and it will bling it up a little.
So. I think I'm back to my original thought of pedal only to do the swap?

Exactly. My HB was definitely not functioning correctly & leaking everywhere. I opted to swap to a Vac set-up to help eliminate clutter under the hood when I started cleaning things up during the motor swap. I grabbed all the parts for a vac brake truck to allow comparisons & the ability to swap if necessary. I compared the pedals & sure didn't notice a difference.

Thus far it's worked but I've been bothered by a repeat leak @ the master cylinder that I hope has now been diagnosed as too long of an actuator pin between the vac canister & master cyl. I do feel the pedal ratio is off personally....
