made by kent moore. part # j 22805-01.
used by many G M dealership techs to replace a power brake booster.
i want to rent or buy a used one.
None available on ebay or amazon nowadays.
if anyone knows where i can find it please private e-mail.
My mechanic has many years experience and drives a Lumina.He can not get the booster unscrewed. He tried tapping it with a screwdriver and hammer,etc.
He worries that it could totally break.
Thanks for any advice.
