Sounds like a sensible approach, particularly if it keeps you safe, and the IVA examiner happy. Being nosey, what are the pair of large vertical tubes welded under the "goal post" for? The Roll hoops fit inside them Link to comment Share on other sites More sharing options...

KugaWestie Posted July 30, 2018 Author Share Posted July 30, 2018 Tonight's little job was to weld in the threaded spacers which will accept the top central harness mount behind the seats. I drilled a clearance hole through the position plate marginally larger than 7/16 which is the size of the eye bolt. The spacer was then positioned behind the clearance hole and welded in. So effectively it is sandwiched in position as well as welded. Link to comment Share on other sites More sharing options...
KugaWestie Posted August 4, 2018 Author Share Posted August 4, 2018 I sprayed the additional bracing and harness top mounts today Link to comment Share on other sites More sharing options...
KugaWestie Posted August 16, 2018 Author Share Posted August 16, 2018 I picked up the diff today after a complete tear down, rebuild with all new bearings and seals and powder coating. It has also been derated to suit the lighter weight of the car. Link to comment Share on other sites More sharing options...
KugaWestie Posted September 9, 2018 Author Share Posted September 9, 2018 Now the Mini is pretty much sorted (until I break it again!), it's time to get back on the Cobra. So I got the newly refurbished diff out tonight, and I must say it's a lovely job that has been done on it. I started by filling it with oil, followed by fitting the discs and brake calipers including lock wiring the bolts. That went well so I carried on and fitted it into the chassis. It's only in loose at present but at least it is in its home Its good to be back on the build Link to comment Share on other sites More sharing options...
KugaWestie Posted September 16, 2018 Author Share Posted September 16, 2018 Car building time is scarce at present, but I managed a couple of hours this evening. I re-assembled the rear drive shafts/hubs/wishbones etc. I wasn't looking forward to this job as I knew how fiddly it was last time! Everything is on, but not torqued up yet Link to comment Share on other sites More sharing options...
Steve (sdh2903) Posted September 16, 2018 Share Posted September 16, 2018 I still always take a double look at those rear uprights. They just look like there's a top arm missing!! Link to comment Share on other sites More sharing options...

corsechris Posted September 17, 2018 Share Posted September 17, 2018 Looking good Gary. When I put one in the Marcos it took me a while to get over the absence of an upper wishbone too. Good job the lower arm is a sturdy thing isn't it...... I'm pretty sure I saw a lower rear brace in one of your earlier shots? Fits between the ends of the inner pivot shafts at the back to keep them spaced. The castings they fit in are beefy, but I'd not want to rely on them alone as they are a bit cantilevered out from the main bulk of the diff casing. I put a 5mm thick plate between them on the install I did, and another at the front that then mounted to the chassis via some Spax bushes. Seemed to cope with the output of the 4.2 OK, although it only make 250bhp/250ftlb With the right spring and damper rates, that setup gives an excellent ride, and having that big lump of sprung weight in the back really helps with traction. It transformed the Marcos when it went from live axle to that cut down IRS. I don't think you'll be disappointed. This was it. Top diff mount was a plate welded to two cross tubes, with Spax bushes at the ends so the entire rear suspension was rubber mounted. Link to comment Share on other sites More sharing options...
KugaWestie Posted September 17, 2018 Author Share Posted September 17, 2018 Thanks @corsechris Yes the rear lower brace is still to be fitted, I will put it on when I torque up Link to comment Share on other sites More sharing options...

KugaWestie Posted September 21, 2018 Author Share Posted September 21, 2018 Grabbed an hour after work today, so put the coilovers on. Again, not torqued up. I did torque up the top diff mount bolts and lock wire them though Link to comment Share on other sites More sharing options...
KugaWestie Posted September 21, 2018 Author Share Posted September 21, 2018 I think I am now at the point where I could pop the wheels on and have myself a rolling chassis! Link to comment Share on other sites More sharing options...
