Has anyone successfully installed speed bleeders on their 122 drums/calipers? I'm preping for a major brake refurb project and was considering installing them if they are available. I've used them in the past on cars that saw frequent autocross use and was really happy with them. I re-applied the thread sealant one a year to keep them from leaking since they were bled so frequently. I'd think on a car that sees more infrequent bleed cycles that re-sealing the threads so often would be less of a concern.

I inquired to the manufacturer about a 122 application and got the following response:

"Tim,

I do not have your specific model Volvo. I have a listing for a ’69 164 series and that takes SB6100, M6 x 1.0 front and rear. What size wrench fits your existing bleeders?"

Does anyone happen to know the pitch and length of the OEM bleeder threads? That might go a long way in finding a suitable part.
