    Sportomatic servo diaphragm required

    Sportomatic servo diaphragm
    Can anyone assist me in finding a Sporto servo diaphragm for my '74 911? I'm losing vacuum due to a tear.

    There is a guy on eBay who makes new ones. I purchased one as a spare, haven't installed it, but seems to be good quality:
