The previously made template was used to accurately mark out where the holes needed to be cut for the rear bracing tubes. A hole saw and a curved file were used for this.
What I hadn't appreciated was that these bracing tubes were at a slight angle. Meaning that the holes had to be widened to get the ends through, before the rear half of the cage could be lowered in to place. Covers will need to be made for these. Probably out of aluminium sheet sprayed white.
The feet were then bolted on to the bracing tubes and holes drilled in the rear of the chassis to accommodate the fixing bolts. All in all not too bad a fit, the fabrication tolerances probably within a few millimetres.
Luckily the off-side bracing tube clears the fuel filler by about 10mm and also the filler pipe below. Phew! That was a close call.
After fitting I tried to get in the boot. Oh dear, we have a problem. Looks like the boot on the Avon Mk2 bodywork will only open to about 45 degrees with the roll cage fitted. Never mind, access is still pretty good.
Next on to the front half of the roll cage...
