I have a very lightly used Tilton starter for sale. This model has a 9-tooth pinion to work with 104 or 110 tooth ring gears. I tried to install this in my Lotus Twincam-powered Formula car but could not get it to fit in my very narrow monocoque chassis. I removed the unused middle ear from the adapter to gain clearance but still couldn't get it to fit. I ended up using a starter without a side-mounted solenoid, so this one is now for sale. The adapter is part number 54-530 and it is available separately if you really have to have that middle mounting ear. I am asking $350 plus shipping.
