I sent an e-mail to TRICO and this is what they had to say
"Our Classic catalog calls out a 33-122 blade which is 12 inches. We do make an 10" as well # 33-110 if this is the case. We also make an adjustable arm that should fit. I recommend you go to NAPA and ask them to look up the 56 Dodge in their classic catalog. If they don't have them in stock, they can order from the main warehouse. We package them private brand for them"
Try NAPA. Next time I'm in their store, I'll check on these. The TRICO 51 series is for older cars.
