The roll cage is now in. I planned to buy some foam to cover the roll hoops today but I realised that’s hard to do on Good Friday.
Supercheap Auto was open and I was able to get a pair of longer M10 bolts and nuts. This allowed me to put them through and do them up tight, pulling the cage mount and the plate under the car closer together. They can then be removed and the shorter 30 mm bolts put in place. The worst part of the job is the silicone that coats your fingers and tools as you play with the nuts and bolts.
Once I can get some foam I’ll cable tie it to the roll hoops to finish everything off 100%. Big shout to my wife for assisting yesterday. She held a spanner on the tops of the bolts while I tightened the nuts in the wheel wells.
