Yes the second one down looks like it.
I know its 7/16 20
I had gone to my local Oreillys auto
He was able to bring up the 50 on his computer, but when he showed me the picture it looked like the knurled shoulder was way to long. Plus he didnt have it in the store.
I'll take your numbers to my local carquest. they are better on this stuff
thanks for the help
