Not sure this is the correct place for this but I am at a dead end. I recently had the ASI in my 1960 250 pulled, believing it was not reading correctly. Turns out I was right it was off by 10kts. So the shop sends it out for repair. Long story short they believe it PN had been tampered with and will not repair it. Short of buying a new ASI for $1200 I am looking for a used replacement to hold me over till November with I put my G500 and ESI500 in. Is there anyone with a replacement I have called a lot of places with no luck.
