Have you considered calling DSS yourself? What you're saying makes no sense unless Pentalab's posted info is incorrect. $320+ shipping is a long way from $100.
Haven't had a chance to call last couple of days, due to work.
Tried this morning at 8:30, got a machine saying their hours are 9-5
I could swear on their Facebook page they list 8-5
Monday I tried calling about 8 times, kept getting the same voicemail message, that they're on vacation and will reopen on Jan 4th, but even though that was Monday, they weren't ready to talk with customers yet, apparently.
I will try to call them tomorrow.
Not sure where the $100 price came from.
RCV Performance has 2 joints that they say will work, one is $120, the other is $210, both plus shipping, both plus the grease they sell for it.
