My first real car was a '55 Pontiac and it actually had a pretty good sounding radio in it. So good in fact that after I kilt it by doing "neutral slams" I felt obligated to install the radio from the Pontiac into my new Austin Healey 100-6.

Only problem was, the old tube radio was so heavy that after installing it, I almost had to move the battery(I converted the two 6Vs to a single 12V for convenience)to the other side of the trunk to mantain the vehicles' balance

....it would over-steer to the right and spin out much more readilly than it would spin out to the left....
