Summary:
ZF trans from BMW M50B25
single mass flywheel and pressure plate from SR but clutch disk for BMW M50 engines.
to compensate distance between flywheel and trans installed spacer for center support bearing.(trans was cut open to get those measurements)
driveshaft has front piese from bmw with retaining center support bearing because of length (this is not s-chassis though)
what im interested in:
which transmissions available at US junk yards preferably 6 speed. what gear ratios? because if 5 speed than simply z32 trans can be used.
is vehicle speed sensor present on bmw trans or signal comes from abs module?
