I have completed the mechanical side
front end completed with HQ front brakes, HT booster, custom cross member and alloy radiator.
Lots of updates but will list the horror and and positive.
The 253 and 4 speed all fits. Went to start after sitting for a couple of years and it just would not start. After grabbing a cool drink the investigation started. Found the fuel had separated with water going to the carby. Drained the fuel tank and carby and went to start again. It then got good fuel and massive back fire which was caused by the dizzy being 180deg out. Then it started but very rich. Huge amounts of black smoke was caused by power jet in the carby being damaged from the back fire. Then it started and allowed to settle but it blew a welsh plug. After drinking most of the cool drink from the fridge now and removing the engine changing all welsh plugs and fitting it, she now runs and idles.
Called around Perth for a radiator and was shocked by the quotes. I bought an alloy rad with spal twin fan fit and hidden overflow from group in Vic.
