Seems to be leaking at the mounting bolt or at least that area under the combination valve but doen't appear to be the lines/fittings. What would be the cause? This is an '82.

Thanks,

Upon further inspection, the leak is at the front of the distribution block where the metering valve connects. Anyone know if there is an "o-ring" or seal at that spot? Would I need to replace the whole proportioning unit? Also, for any Canadians in Southwestern Ontario. Where are you getting these? I do see Summit Racing has them but of course will be the shipping charge.

 

Had valve RSD-PV71 from Summit Racing put in. Is direct relpacement and does look like OEM. Mine is disc/ drum. So far feels good for not locking the rears. Did cost more to ship/customs than the retail but if it lasts 30 years like the original no complaints here. Total cost about $180 cdn, installed.
