[Zwap]

Nice! From where did you ordered that?

 

[polara71]

The title suggests to me Dr Diff

 

[saylor]

[CanCritter]

lve got a 4,11 tru track in my 91 gmc...little noisey for my likeing...works fine..dose what its supposed to do

 

[saylor]

i cant wait my ESPO springs n things just got here yesterday (thanx laura!) , so i have all the parts now to change out the whole business back there on the south end.

@horvaths - wheres a good rear diff shop around town for a gear swap ?

- saylor

 

[polara71]

I woulda just sent the center to Cass and let him operate on it. You KNOW it will be right

 

[saylor]

@polara71 - yes :/

between the cost of parts + the cost of the R&R of my 741 case - and cass offers a built 489 case for like $1100 or so..

but yes. i went the long way :/

i didnt know.

 

[polara71]

Ive looked his site over and he sells 489s for under 1400 which is a lot of coin. Rebuilding a unit would probably be half that..... I hate taking stuff to guys Im not sure about

I have a good differential guy in the San Antonio area. If you provide the parts he charges 250 to rebuild the 3rd member. Jason

 

[saylor]

ya man $250 + lunch at rio rio hell ya

I have a good differential guy in the San Antonio area. If you provide the parts he charges 250 to rebuild the 3rd member. Jason

So if I took him my open 742 case, a true-trac, and 3.23 gears he can put it all together for something Like $250?

The guy I know of I would never recommend. Maybe try posting on the Cowtown Mopar Facebook page.

 

[68plymouth383]

You'd need to provide the bearings, seal, and shims. The complete package everything needed to swap it over.

@horvaths i may go talk to ol jeff @ plano transmission and see who he says... hell maybe he will do it even.

as much as i like san antonio, thats a helluva drive. too cold for schlitterbahn yet too

 

[saylor]

for you poor bastards that will never get to go to schlitterbahn . . .
a long time ago, this dude took part of a river and diverted the water flow some, and made a kick *** water park right on the river edge, using the natural spring fed river water.. several of the rides are *in* the river, or dump you out into the river at the rides exit. you can also go tubing or rafting or whatever.

 

[68plymouth383]

It is a drive. You could ship it, and I'll drop it off... but that would be probably 100 bucks each way in shipping

@horvaths i may go talk to ol jeff @ plano transmission and see who he says... hell maybe he will do it even.

Jeff's a great guy. He built the trans in my Blue Moose and my dad's Satellite. Good luck with it.

Looking to do the same thing for '68 New Yorker. Mine has a 2.76 open ratio. I think 3.55 would make it come alive. Let us know how it turns out.
