Did it work? I seem to remember now, that i heard this before, but that it only worked on the obs trucks. Like to hear that it works for the sd trucks,cause i need it to badly.

I've seen this acronym too many times....what does obs mean?

 

[DaveBen]

obs = old body style. I had that same question and it took me years to find out. I did not ask.
