Joe,

I'll try to nail everything in one reply:
630151 is only an option on the Independent suspension.

I'm working on trying to find rebuild parts for the Norgrens (haven't tried tackling that one before), and I spoke with a Tech who just completed the burkett to norgren retro and got some scoop. I'll be here at the office the rest of the week, so if you get a chance, give me a call. 951-360-2550.

I'm working on an article that should help explain in lamens terms(or parts guy terms, whichever you prefer) the conversion process. Will update soon on the norgrens.

And I agree completely that they called the race at Daytona too soon. I can't believe Kenseth cried. Sheesh....
