I just received a limited shipment--after waiting four months--on the G & D grosse jet (needle/seat) for 48 IDA application. These are used to replace the OEM which are prone to leak.
I have one or two sets of the race version (track only). Let me know if you have an interest. email:
dhampton@rwbaird.com.
Cost: $48.00 for the street version (set of 4)
$75.00 for the competition set
