A better dana 300 twinstick

Rockape and I got tired of the crappy twin sticks on the market (Rockape is ditching the blingin currie setup for these), so we decided to build our own with out the extra slop associated with traditional twinsticks. Here is a parts list....
6 inches of 1 inch round tubing with a 3/16 wall
4 feet of 5/8ths solid cold rolled steel
Plate:
2 inches widex6inches long 3/8ths thick
1 1/4inch wide x 8 inches long 3/16 thick
Bolts:
2) 5/8ths x 3 inches long
2) 5/16" bolts 1/2 inches long
10) 5/16" washers
Rod ends:
2)5/16ths female heims rh thread summit PN SUM-MSF5
2)5/16ths male heims rh thread summit PN SUM-MSM5
If you cant find the 1 inch 3/16 wall tubing then get 1 inch 1/4 wall.But if you do substitute 2 of the 5/8 BOLTS for 1/2 inch bolts(same length).
Rockape has the original drawing, maybe he will post it up, otherwise, this is pirate, figure it out . Here
All in all I spent about $70 for two sets of twin sticks.

Good to see you did it yourself, but...
I don't see how that's an improvement really.

Your connections aren't in double shear anymore, could get sloppy more easily than the Currie set, which keeps it in double shear.
You've got a hell of a lot more leverage on the shift forks now due to the length of those shifters. They(forks) aren't gorilla strong to begin with.
Your connecting rods aren't in line with the shifter rail either.
The bolts through the shifter rail are too short, not even a full nut.

How did you have your other store bought twinsticks set up?
If you don't have the right parts cinched down tightly in line with each other and the other parts loose, it will shift like crap. The geometry is important.

The first improvement is it only cost $30-35bucks to make.The second is it doesnt have the looseness like the currie junk(shift levers are 5/8 not 7/16,the levers also pivot on a sleeve, not thick washers and heim joints have alot less free play than little 1/8inch strips of metal.)
And your comment about double shear??You say the shift forks arent "gorilla " strong then why would you worry about double shear??
And being out of alignment,that why there is heims on both connection points to allow for a bit of misalignment.
I think that the reason he posted these pics is to not say these are way better than someone elses but to show why buy, when you can make them cheaper and better yourself

Not trying to bash ya but............................ I'd pay the extra!!! You can get the other no name brands which are basicly a copy of the Currie units for about $70-$80 now anyways. Might be even cheaper now. As long as it works for YOU and YOUR happy then that is all that really matters I guess. Still looks pretty Getto Fab.

This is my last comment on these less than average quality home-built shifters that should have never seen the internet.
Your connections will see more leverage placed on them and could loosen more easily because they are in single shear. Double shear gets rid of that leverage.
It will not shift as well if it is out of alignment because the forces from the lever aren't in line with the shift rail. Heims have got shit to do with that. I'm talking about what you need to do to keep it from binding.

Not crazy about how you did it But like the theory behind it using the mini rod ends. Here is how I got started on mine. Used 3/8" rod ends, sorry no finished pics as I am still working on it. "It" being the whole Jeep ....

Kind of off topic, but I was wondering if your d300 was clocked flat. I want to see how much floor needs to be removed in order to stuff one in an xj. If you could post up a pic of how you cut your floor that would be sweet.
Thanks in advanced

Good luck getting one to clock flat, not saying it can't be done, but on my MJ I cut a hole approximately 2'x2' and I would have had to relocate my seat to make it work. Mine is now clocked at about a 45* and it still doesn't hang down too far.

Mine is flipped and twinsticked...

I've had my Currie twin sticks for 3 or 4 years now with no issues... I don't have this slop you talk of. Maybe my shifters are set up correctly?

I hated the twin sticks being on the floor so I moved mine up and made them adjustable:

Looks pretty cool. I know I'd screw up the first few times trying to remember that the shift pattern is now backwards!!

Ok, so are you saying that your twinsticks don't wiggle a ton? I am sorry, if anyone could set up a twinstick, it would be rockape, he is a mechanic for honda and has built a ton of rigs (including 2 tube buggys that work badass). Yes, the currie works great, but it is too sloppy for our liking. This is Just another idea, if you don't like the design, post up something that is better ...

That is why I am putting stickers on top to remind me which direction to throw the lever in.
