I have a pair of VERY RARE 16 x 10 two-piece ET III wheels. They are aluminum (even though they look like magnesium). The bolt pattern is 5 x 5 (Olds Pontiac) with 4 inch backspacing. These wheels were made specifically for drag racing to allow teams to change tires at the track simply by taking apart the wheel...you didn't need to run and have tires mounted. These were made famous by Don Garlits, KS Pittman, etc. The wheels have been in storage for over 30 years and are in excellent shape. There is one small gouge in the lip, but it will not be an issue since you have to run tubes with these wheels. These wheels need to go....I need the money to fund a project. Send me a message or call me at 414-793-4976. Thank you.
