I installed them happily on a 1976 Seneca II.
It is a great product but the company is slow in reponding to requests for info - typical of most aviation suppliers in the USA in the 20th century. Somewhat slow off the mark in not supplying anything but a USA toll free telephone number. Like pulling teeth.
