Could anyone tell me what thickness spacers i need to fit 15" Radars on my 68 early bay. I've just bought a set off a guy who had them on a Splitty, and he supplied all the spacers and bolts etc. I've fitted the spacers but the tyres rub on the side of the arches as there is no clearance. It seems having a closer look that there is still a little clearance inbetween the hubnut and the wheel center which would probably allow the wheel to just sit slightly closer in thus giving a tad more clearance on the tyres. Cheers for any help :?
