Yes pretty sure Mike he has the trans in two gears at once. I wish I could find a picture to show him, but if he first flips his shifter top over he will see the 3-4 shift yoke which is the smaller yoke, there are three positions for this yoke , make sure it is in the middle detent, now you may not be able to move this yoke if the 1-2 yoke is in any other position other than its middle position, if thats the case move the 1-2 yoke to the middle position first then the 3-4 to its middle detent.
Once the shifter top is adjusted then move to the gear box and make sure the 3-4 slider is in the middle thus exposing both the 3rd and 4th syncro (see this picture attached), then adjust the first gear by sliding it along the main shaft so the dimension is 4-3/8" between the outside of the 3-4 slider groove to the outside of the slider groove on the first gear.
Drop the shifter top on the gear box making sure the reverse lever slides into the head of the shifter top.
This is one of those things that is hard to explain but really easy to do.
