Topic: Couple Dual Case questions

[FatAzzRunner]

Hey guys,

I know this is a dumb question to a lot of you but here it goes.

I am fixin to order a cluth kit, dual case adapter, speedo extension, heavy duty shift springs,  and a dual case skid plate.

I want to make sure I do this right and not have to do this again...............


1.  Am I correct in guessing that I need 4 of the heavy duty shift springs?

2.  When I go online to order my dual case adapter(MC 07), it asks if I want a 21 or 23 spline.  I already have a 4.7 case that I ordered from MC  about 2 years ago and I would assume that it came with a 21 spline input shaft.  Do I need a 21 spline or 23 spline when I order my MC07?

3.  Also, I understand the directions that if I already have a 4.7 case, I need to put it in the back due to the torque involved in dual cases.  Is this correct??

4.  Anything else you guys can think I might need..........besides a clue??    

Thanks guys.

1. nope you need 3 total, for the front case shifter and 2 for the rear.

2.  21 spline to go behind your W56.

3.  Yes use it as the rear case.

4.  Myself Id suggest the twin stick shifter too.  I love that damned thing!

Dont forget a second transfer case mount

Yea you would use one with that crossmember wouldnt you.  Im only running one with my setup but its all chained down.

Huh?   See, I must be dumb.  I cant see why you would need a second tcase mount with a dual case skid.
 

WT, you say yours is chained down. Will it be fine with just the dual skid or do I NEED to chain or secure it down somehow?  I have never heard of such a deal.

[WHITE_TRASH]

If you dont chain it down you'll break your exhaust and rip the driverside mount apart.  (this is experience talking)

With the Marlin mount it has a second mount location built into it so its simple to add another mount for increased strength.  Id still chain the motormount down either way.  

Myself Id either make my own crossmember or go with a flat budbilt but if your not lifting the setup marlins is just fine for you.

Yeah, I had thought about goin flat belly but I dont know if I have the time to mess with it. 

It seems like a lot of work but I know it would be well worth it.

We will see what happens I guess.  We are plannin a big trip to Colorado in August of "06 but I am working 7/13's and there is not much light at the end of the tunnel for this ending.  I may be lucky enough to get done with this crap in time to do something like that but not sure at this time.
