Billet gearbox end cover Porsche 993 G64/20/21
Code: CMS.993.EC
cms

This conversion was originally designed for mid-engine installations using an AWD 6 speed transmission - but can also be used in rear engine applications.

The end plate is available in two versions, 5 speed G50 or 6 speed 993 and with or without a provision for the shift shaft. This conversion requires either the c4 5 speed or c4 6 speed gear housing to be used in conjunction.

This can be useful for 6 speed AWD to 2 wheel drive conversions, or to replace the no longer available 6 speed 2WD gear housing.

Note: Please specify whether you want with or without shift shaft provision when ordering. The price is the same regardless.
