Loom is going to have to wait.
Went to start it last night, and thought I need somewhere to attach it in the engine bay.
Started modifying my old brace bars. Pics attached of tacking the brace bar up, and after they were both fitted. They will bolt to wee brackets welded to the subframe.
Also discovered a wee "issue". I can't insert the inner driveshaft joint on the passenger side with the engine in. Looks like it needs a wee bit removed at the top of the shaft hole in the subframe at the bottom of the tower. Its close when its in, but ok. Want it removable with the engine in place however. Maybe 15mm of steel removed at the top will suffice. The exhaust is also close at the other side, but will heat wrap that area of the exhaust to prevent heat damaging the CV boot. Its maybe 15mm away or so.
Will finish my brace bar mounts, then mark up any mods that are required on the frame (wee bit more clearance where the exhaust passes the front crossmember and bit more under the gearbox), and strip it all down again for these mods and painting.
