Bought part Thru Another Supplier
I ordered the parts thru Replacement parts because they had a bracket I needed. The cable was more expensive than another site I went to, but they didn't have the bracket.
I purchased both parts here.
In the end it took 3 months to get my order because it was back ordered and although they didn't tell me until after I purchased the parts, that they didn't have it either.
As I said, it took 3 months to ship and mean while I was able to get the parts in hand from another vendor.
Not Impressed at all.
