Thank you!!
I was going to dive into it tomorrow, exploratory style.
You saved me a lot of cussing.
Thanks Gill!
I called Merlin the other day. He showed that the two were different part numbers, but couldn't physically look at them because they are out of stock... in fact, ISUZU is out of stock. They are on back order.... for a long time.
So, I need to look for a right hand one now.
Mystery solved. Hope this thread helps someone else too.
Lesson learned: Do NOT buy the one that parts places sell like the right hand one in the pic above.
Thank you!
