I bought this lockup brand new from APE few years ago. I installed it on engine sitting on workbench but has NEVER been on a running engine. I tried finding someone who still sells them new but didn't have any luck (APE might still sell them, not sure). Pingel has them listed for 350.00 but they are unavailable. Selling for 250.00 shipped to lower 48. No trades please, need the cash.
