I found one that I think will work it cost me $1.00 at a slvage yard. It came out of a early 80's van. Can someone measure theirs to see if it will be long enough? The one that I bought has a bolt length of 2" and a shoulder width of 1". I would check it out on the truck but I won't be able to until the weekend. I have picks below.
