Tim,
I have spent considerable time over the years looking into M/C's from
different cars. The vertically oriented bolt pattern of the Tiger is not
often found. Mazda's (not sure of year, but I recall RX-7's), Nissans
(actually Datsuns back then) from the 1970's are about the only one's I
recall with the proper pattern. In addition to finding an appropriate bolt
orientation, there is a matter of where the brake line connectors exit the
M/C and how it attaches to the pedal. Nissans are downward and most Mazdas
to the side. Almost all the M/C's come off a booster, thus one is left to
"adapt" the rod between the M/C and the pedal. This can prove difficult
because a booster M/C often has a much smaller rod contact point with the
M/C piston AND there is no provision to keep the rod from falling out of the
M/C should the pedal somehow come loose.
In my case I used a near new replacement I found on a Datsun 710 from
Pick A Part ($10). I also poked around and found a rod that was from a
non-booster car AND was adjustable (very hard to find). In this case the
appropriate rod was from a Volvo 122 (1960's vintage). I still had to grind
down the nose of the rod to properly fit and actuate the M/C piston,
carefully grind down the M/C retainer (that is held in with a clip) and
slightly bend the piece that connects to the the pedal before it all was
functional. Lastly I NEVER found ANY adapters that would allow connecting
the Nissan's metrics into the Tigers lines. I spent hours upon days looking
(including suggestions from the list) and got nowhere. In the end I am going
to just use a hybrid line with appropriate connectors reflaired (which
basically forced me to but the tool that cost three times what I paided for
the rest of the conversion).
You also mentioned a 13/16" M/C. Almost all of the M/C's I mentioned are
11/16". In my case I am not running a booster and was fortunate to find the
Nissan in the 3/4" size which is not too common. While it is not an
impossible task to adapt a different M/C it can be time consuming. If you
are not incline to "tinker" going with a kit that has already been thought
out would result in a more pleasant outcome.
