I have had my 15" LF drivers re-surrouned by OCSR and the results look good, however there was a gasket/s (as I recall) that sat ontop of the driver to space out the hold down washer and cap nut. When OCSR sent the repaired drivers, they sent new gaskets that don't seem to be wide enough to provide enough surface area for the hold down washer and cap nut to secure to. If I try to hold the gasket to the outer edge while tightening down the washer / nut, the gasket deforms.
I have attached a couple of pics to help convey the problem.
Can anyone with 813 experience verify my memory and the hold down architecture for the 15" LF driver?
Thanks,
