Topic: Need help with cases

[AaronB]

OK, I am running dual cases with a twin stick mated to a turbo350 tranny. The front case is a forward shift and the rear case is a top shift. I dont see how the rear case and the front case are going to work together.
What do I do with the shift forks on the front case?

convert it to a top shift..... you cant use the forward shift thing because you arent using a tranny that can do that

are you sure? the AA adapter has a slot cut out so you can run a forward shift, the rails arent going to be attached to anything in the tranny itself.
Im thinking, I will have to run a shifter in the front case. 

[AaronB [OP]]

like this, but of course the rail will be inside.

here is what I got. Look at the difference from the shift rail and shift fork pin hole with the shifter.

I think im going to have to weld the key stock to the shift rail and run a shifter in the front case. What do you guys think?

I have been though this. it took me about 3 hours of cuting and welding to get my forward shift to work with the aa adapter. the big think is i had to cut a hole in the aa adapter to slide the shift rail out the front a few times to get the cut and fork welds right. and i did it all assembled in the truck. i think i took a 1/2 off the end to get it to work. you have two shift forks get to cuting and welding.

Looks like you need the shorter forward shift rails.  My th350/yota adapter from AA had the shifter in the front too and it was a direct bolt in deal...

uhm why not mark the shaft where the hole needs to be, drill it and then hack off the excess in the rear?

[AaronB [OP]]

this is were i ended up, just need to notch the area marked in red.

[Duffil]

Why do you have to notch it? the shifter pivots from the center.  Is the adapter not cut correctly?

edit: looking at the shift hub, that is in high range? why not slide the shaft forward and drill it?

[AaronB [OP]]

its actually in neutral in the pic

[Duffil]

I see now you had the fork the wrong direction earlier.  is there enough shaft to still be in the backside of the adapter and redrill the hole?

[AaronB [OP]]

yeah it was backwards. i actually dont have to redrill it, just notch the AA adapter were i had it marked and make a plate to mount the shifter.
