I miss spoke. It's not that they spin opposite directions, it's that the discs are reversed.

Both of these are facing the pressure plate.
what works.



what doesn't work

Throw-out/release bearing updated numbers. The "known good parts" page needs updated, so here is some current info.

my throw out bearing died on me, so I had to search for a new one. There are two kinds: Long and Short

Short: #614018 This number is used by many manufactures like Delco and National. Prices range from $11 to $45 ($67 at NAPA) for the same part.

• Bore 1.3775"
  Face 2.76" this is the part that touches the fingers of the pressure plate
  Height 1.252"

Long #1625 or NATIONAL G1625C

• Bore 1.3775"
  Face 3.0625"
  Height 1.699"

Just measure the face of your old one to tell which one you need. Mine is the short one and seems to be the common one. I was able to find it in town at all the major parts stores and of course Rock Auto. Rock Auto has some of the long and short descriptions wrong, so just go by part number and the dimensions.

11"Disk: none of the numbers on the "known good parts" page work anymore.
Nobody has this. As of now the only options are to get yours rebuilt or have a new 12" disk modified (flip it around. see post above)

---
12" pressure plates are easy to find, but it seems like you need to get the whole kit for those and the disk will not work out of the box and will need to be modified. The good news is the kit I bought had the short clutch release bearing and the pilot bushing would fit as well. It seems all the kits come with the short throw-out and a disk that won't work.

I was told the Rhino-Pac/Platinum 04-528 was the only clutch kit that would work right out of the box with no modifications. It's a 12 inch, and supposedly the disc hub is assembled the correct way for the flat V-6 flywheel. I personally never used one, I had my original clutch rebuilt years ago. The 04-528 has been on back order for several months.

Rockauto once again has the Platinum Driveline 04-528 clutch kit in stock as of this week.

Rockauto notified me the clutch kit was once again available, I ordered one, and today they notified me it was out of stock! Typical Rockauto B.S., sorry for any confusion.

it's usually just a renewal notification. anyways, you can delete it. There is a new kit available.

That's the funny thing, I was getting notifications to renew the backorder. Then last week I got a notification is was available to order, which I did. Then a day later they said it wasn't available and refunded the charge.

I finally managed to get everything together for my 60 4 speed with the help of Capitol Clutch and Brake in Sacramento. They were super helpful with a really tough problem.

So, I get a notification from Rockauto this morning telling me the M-Pact 04528 equivilent of the Platinum Driveline 04-528 is available to order. I went ahead and ordered one, we'll see what I get. If anything!
