Thread bump because I did a thing (in addition to those bits and bobs mentioned in the general weekly thread).
As I’m going to be fitting an S14 gearbox to the project, there are a number things that need machining, fabrication, etc., to make that happen. One being something I did the first part of years ago, but left the difficult bit until this evening - modifying the gearbox crossmember. For the uninitiated, the gearbox mount point on the S13/14/14a 71C box is 35mm further back than the 71B Z boxes. Meaning that the corssmember needs adjustment accordingly. My car, as an early 72, has the two piece crossmember (same as my 71 Fairlady Z). There are various ways people have done this, but I went with the “proper” way as taught to me by the great Pmac when I put an S14a box in the Fairlady Z!
Basically, the cradle part (which I did years ago) requires a second hole for nut access making and the back upright section clearancing for the rubber mount when it is further back.
Easy enough (especially as is done this part before). The fiddly bit is the bar with the scroll ends. The Pmac method is to cut it into three, offset the centre by 35mm, and weld up with reinforcement. Pete used to have a jig for this; I had to do a lot of measuring and firm clamping:
Done!
Modded versus original:
Just need to do a bit of weld tidying and edge finishing before painting or powder coating. But another small to-do ticked off the list. Need to start doing the actual gearbox mods…
