What is a good stall to go with a 3:23 Sure Grip?

Your 904 didn’t have one what? Are you talking about torque converters? If so I don’t think I’d ever ever pay $1595 for someone to rebuild a torque converter! Yikes.

We are talking differential Center section I think? Which by the way I doubt anyone would sell a core 742 or 489 case suregrip for $100.

That $1595, plus maybe 500 for a core (if you’re lucky) and shipping both ways will not be 1595 for long….. so essentially they are charging you $1595 for gears and bearing and labour? What’s actually included in that price? And what exactly were you talking about?

Sorry, yes I can see how my jumping between needs could be confusing. My bad.

1) No, I'm talking torque converter. TCS out of Langley BC specializes in building them based on specific application and engine spec. (www.tc sproducts.com) Go have a look and see. They've been doing it for 60 years so they must be doing something right.

2) As for the diff section, yes I need one of those as well - Sure Grip with 355 gears, or 373 even, maybe. If you have one of those lying around I'd be interested in knowing how much there too.
