The one on my W55 has a radius elbow (curved).
Have you done the input/output shaft test to determine 1st gear ratio in your gearbox yet Matt?

" The only true way to know which set of ratios you have is to count them. Here is an example of what to do with a W* series box.
1. Count the splines at the output shaft of the box.
2. Put in gear, not 4th cos thats always 1:1, but one of the others. Do all of them in turn.
3. Mark the top of the input shaft and the top of the output shaft with a dot of twink/white-out
4. Slowly turn the input shaft one rotation and get a mate to watch the output shaft.
5. Count the number of splines on the output shaft after one turn.
6. work out the ratio as follows:
ie. 21 Spline out-put shaft,
3rd gear, 1 turn of the input = 15 splines at output shaft

15 divided by 21 = .71
1 divided by .71 = 1.41

So ratio of 3rd gear is 1.41:1 "

Got the mount today from Paul Dunstan. It's made to suit an auto tunnel MK2 so should go in without dramas

Just need a new mount & a speedo cable and all sorted

Cheers,
