Noticed you had posted the same question in two different forums. That is not acceptable on Stovebolt.com. May I suggest you hop over to the General Truck Talk Forum and read the “Sticky” thread at the top of the page about why things are moved, modified and edited. Lots of good information there about how to use the site.
Oh, sorry. I didn't know whether to put it in the Big Bolt or generic engine section, so that's why I did both.
