Cheers that looks like a proper job do you know if hey are much longer than a standard box ?
Cheers andy
at least 2 inches longer than a type 1 box, with IRS you can move the box into the car more,better than with swingaxle were you are screwed and it moves the engine back.
To answer your original question, a Mendeola MD4 drag[still over 2inches longer than a type 1 box] can be ordered with the provision for the Vertigate shifter, mine is that way, and either syncros or Pro ring/slick shift, the 2 things are not connected, the vertigate shifter is how the gears are selected, the syncros or pro rings are how the gears are engaged.
But none of that will not overcome the fact that your cage etc is in the way of the path the shift rods would take.
My flywheel to starter distance is still not ideal and really the case needs machining where the starter bolts on to bring the starter in more, but I believe there is more of an issue with the flywheel you chose, supposedly its way off where it should !!!!!!
