I stand corrected! I moved poor Marty out west. If you need to contact him directly for the recalibrated oil pressure sender unit his REAL address is: Wing Wirx Inc. 704 Valley Dr. E. Alton, IL 62024 When I purchesed my sender the price was $35.00. Contact him for the latest pricing and availability if you are interested. Just for the record I am very pleased with the way my gauge operates now with his sender. It is very easy to install even if you are a mechanical novice!
