Outer Limits 4x4 Board

I am putting twin lockrites in my yn67 and am very interested in the leavers that lockted up sell for hi vs low and 2 vs 4 for the gear driven transfer case, has any one had any experance with them?? cos on paper they seem that best set up for me...
Any input/storys on this would be great!

I think ya talking about twin sticks. Yep they are good to have. Gives ya 2wd low range. Can come in handy now and then.

I made my own. You need to pull apart the transfer and take out the interlock pin. Not too hard. Could try to knock out the pin then shake the box upside down and to to get it out that way but easier to pull apart.
