questions re fuel tank and alloy wheels

[tassie targa 76]

G'Day All

i have a 76 fuel tank and i would like to fit a full size spare wheel, as in the early models.

having trouble locating an early tank so i was wondering if anyone had cut the top of a tank and modified it to take a full size spare.

i have read stuff about swirl pots and my question is

is there enough room inside a middy tank to cut a piece out.

second question is about polishing alloy wheels i have removed some of the paint on my wheels and the spoke part shows some signs of the original casting.

how do i polish it with out scratching it i have tried steel wool and cutting compound bit this is not enough.

any suggestions

Regards Michael
