Hydralic clutch for 65 Chevelle

I put a 6 speed in my 65 chevelle(it had a auto) problem is it has those electo hydralic brakes like hydro boost except the pump is electric and remote mounted. My problem is there is not enough room becide the master cylinder for the cluch cylinder and everybody I fide uses a short stroke 3/4 inch cylinder for the clutch what I need is a long stroke 7/16 or so cluthch master to keep it from being so hard to push and such a short release motion any ideas. I bought this as a "complete kit" LOL for this car and it has been a nightmare I now know why my 64 and 32 both have autos.

I'm sure you know that you can purchase every piece of the mechanical clutch linkage from the aftermarket, brand new. Throw that hydraulic mess over the fence and go simple.
