Thanks a lot for the quick answer, Rob!
More and more parts of my truck depend on information that you provide!!
I had seen this thread but I would like to know the length of the bolts. If the two bolts provided by Bwoody are the upper rear ones, the spec is mentionned in the document provided by Bwoody and pictured (but not clear enough for me to read it...).
Thanks for the offer to crawl under your truck. No hurry in any case!
