Adapter
includes upper cap (with factory GM gasket), lower bracket
and 2 hardened steel bolts. Brake fluid reservoir (shown in
photo) is NOT included. Red Euro cap is NOT included.
NOTE
- this GM adapter requires the use of a
Euro cap adapter (45mm round threaded cap) which screws onto
the top of the Ultimate Garage GM cap. Assenmacher
TA18 adapter cap will work and can be
purchased online through various online dealers. Ultimate
Garage no longer offers the Euro cap. The Motive 1100 adapter
has worked in the past although Motive may have recently
re-designed the cap and it may not seal properly without a
double gasket or other workaround.
