I'll start out with - I am 65 and not the smartest technical person.
So, I contacted the 800 number while I looked online. I identified the part and the customer service rep confirmed. I wanted to Pay with my Pay Pal account so I had to order online .... it was really quite easy. I paid for "quicker" shipping which was an extra $3.00 - had no idea it would be here in 2 days! Great experience - I will use this site again.
