Hi All, planning a simple and effective shifter on my McLaren M1 replica with SBC and inverted 930. Driver sits RHS, shifter on extreme RHS. Have scanned the archives and found nothing that answers the question I have.
As I understand it, standing at the back of the box the 930 shift pattern is anticlockwise-in = 1st, out=2nd, clockwise-in=3rd, out=4th. Reverse hard anticlockwise and in.
I have built an ultima GTR before and wanted to follow that general rod-style approach, but given the shift pattern above it looks like I don't need to reverse the movement of the shifter knob before it generates rotation and fore/aft movement of the main shift rod, and the shifter can literally be a completely solid rifle-bolt rod with a handle and knob simply welded on directly.
The fore/aft component of the shift would be short, but otherwise would it be OK, and would the H pattern that resulted be conventional?
Thanks for your help.
Cheers, Andrew Robertson
