Not that I remember, but installation only consisted of unbolting the
stocker, bolting the Byars conversion in its place, and fabricating two new
brake
lines to fit the GM master cylinder. The Byars conversion involved them
chopping the 4-stud GM mounts off the booster, welding three new metric
studs
in place to match the original Pantera mount, then gold-alodine coating.
Uses
stock nuts, washers and the stock pedal pushrod. It fit but was close on
our early L where the inner wheelwell edge snuggles up to the brake booster
cannister. On some cars with heavily upholstered front trunks, this is the
only area where you might need a small dent. The aluminum GM master cylinder
has a built-in 2 lb   pressure-hold valve to the front calipers, saving the
cost of adding one.
The two fabricated lines take SAE flairs, not Euro bubble-flairs; they need
to be fabricated because the two outlets are both on the inner fender side
of the master cylinder, which does NOT protrude at an odd angle nor stick
further into the front trunk space than stock. Finally, paired with certain
clutch master cylinder adaptions, the slightly larger dia. brake booster
gets
very close, and a little file-fitting might be needed. My aluminum Girling
clutch master fit unaltered as did a stock iron MS, but there are many such
combinations possible.
Incidently, it's been in our Pantera for 6 yrs; 2 yrs after I installed it,
the plastic vacuum exhaust valve housing cracked for unknown reasons
(protrudes into the cabin thru a big hole; I might have done it myself) and
Byars
overhauled it free of charge. GOOD service! FWIW- J DeRyke
