This transmission crossmember holds the rear engine insulator (rubber transmission mount). The crossmember matches the car, while the insulator matches the transmission type.

With a B310, custom crossmember are relatively easy to make, as there are three holes on each side of the B310 tunnel. For example, this long-tail 71-series crossmember is fabricated out of 3 strips of metal and uses the stock rubber insulator:

5-speed

5-speeds have their own gearbox crossmember. If you can't find the right crossmember, you can use a 4-speed crosssmember with 20 mm spacers.


Buy from Pitroad 20mm spacers


* 5S5W60L no spacers needed, use F4W60L xmember * F5C56A 20 mm spacers on B110 crossmember * FS5W60A 20mm spacers on F4W60L xmember * FS5W63A use B110 automatic crossmember

There are different types of rear insulators.


The 56-Series Transmission type of mount bolts to the crossmember from the sides of the mount, just like these stock 1200 mounts:
