A couple of months ago, I put a WTB ad in the Classifieds section for a pair of the flat bar type OEM rear seat support brackets like this: John (Johns1967CJ5) very kindly sent me this full-size tracing of one of the original rear seat support brackets from his '67. Since no OEM brackets had surfaced at that point, I'd intended to measure the dimensions from this sketch in order to have a couple of them made: However, shortly after I received John's tracing, Mike Starck did me an enormous favor by sending a pair of OEM brackets from a mid-70's back seat that he didn't have a need for (thank you again, Mike!) This photo shows John's tracing overlaid with one of the brackets Mike sent: It turns out that the two bracket designs are/were basically identical, with a few minor exceptions: a diagonal gusset of 1-1/2" x 1/4" flat bar stock was evidently added at some point during the AMC years; the horizontal front "foot" is about 1/2" shorter on the 1970's bracket; and the hole previously located in that foot was deleted in the later version. These drawings show the dimensions of the OEM bracket, as measured from the mid-1970's examples Mike sent. Hopefully these will suffice if someone wants to make a pair themselves, or have them made up by a shop: Also note that jwmckenzie previously posted excellent drawings of the OEM rear seat retaining brackets / straps (which bolt to the bed and the above support brackets slide under) and locking pins here: Rear seat install Question Once I get to it, I'll start another thread to show how I'm adapting the OEM brackets to fit a mid-60's Jeepster rear seat I recently purchased and am having reupholstered.
