For helping keep this great
old truck web site

Again, thanks! | | | | Joined: Jul 2005 Posts: 169 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 169 | Did some searching but did not find what I was looking for. Are the running board brackets the same for a 1/2 to 3/4 for AD trucks? These would be the brackets riveted to the frame.

Same part numbers for middle bracket left and right. But for the rear, it looks like a different part number for 1/2 and 3/4 ton. | | | | | Joined: Sep 2007 Posts: 2,644 Shop Shark | | Shop Shark Joined: Sep 2007 Posts: 2,644 | Did some searching but did not find what I was looking for. Are the running board brackets the same for a 1/2 to 3/4 for AD trucks? No, the front two are the same but the rear ones are different to accommodate the extra length of the RB. The half-ton's are angled foreword. The 3/4 ton's are straight. In the Facory Assembly Manual there are plan views of frames where you can see the exact dimensions. | | | | | Joined: Jul 2005 Posts: 169 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 169 | You guys are great!!!
