Why are there so many inspection covers (6) in the back of a 1958 Panel? They don't seem to serve any purpose. Or are they used for something on a Surburban? Here they are. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | they're called 'access covers' in the assembly manual, same in both body styles, the back 2 are to access the wiring for the taillights, no explanation for the others, so they likely have to do with some procedure at the factory

They are handy for getting at the nuts that hold the fender bolts. | | | | | Joined: Sep 2006 Posts: 3,596 'Bolter | | 'Bolter Joined: Sep 2006 Posts: 3,596 | | | | | | Joined: Nov 2012 Posts: 77 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2012 Posts: 77 | Wow...I know yours is an AD, but don't recall having those in my previous TF. My current TF has a finished interior(for now)so I can't see.

Bill I missed catching the photo link. Thanks, Bill. Okay...gigantic flashback to my 55.2 in '68. I don't think mine had covers over the holes, just like shown in the photo. I think we stuffed trash down them...hey, I was only 16!

Interesting that they changed the design when, as Bill said, the only useful ones are at the back. I guess they might be handy for pounding out dents although they haven't provided much help with my bodywork. | | | | | Joined: May 2005 Posts: 8,983 Sir Searchalot | | Sir Searchalot Joined: May 2005 Posts: 8,983 | There are braces between the inner and outer "bodies" of TF burbs and Panels. I always thought the access holes were for MFG, as stated, to get a spot welder or hand welder in there for those braces or other welding procedure. Since I always take the tail light off from the outside and let it hang for re-wire or servicing. Rear speakers fit in there nicely. 
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn | | | | | Joined: Feb 2012 Posts: 506 'Bolter | | 'Bolter Joined: Feb 2012 Posts: 506 | They are also for accessing the retracters and cables for a clam shell rear door set up. One of the forward holes gets you to the retracter mounting point. The rearward one gets you to where the cable meets the retracter tape. Without looking at it, I can't remember which is which. If you have barn doors you won't have to worry about it.
I'm in the process of trying to find cables for my 58 Burb with a clam shell rear door.
Thanks
Larry

The Assy Manual, sheets 115 and 116, shows the reel at the center access cover and the clevis pin connection to cable at the rear access cover. (I think). The maintenance manual shows a picture in Sec 3, pg 160 that says reel is in "front access hole", but verbage on the next sheet says "center" access hole. The picture in the ASSY Manual shows center access hole between side windows. So the place it says "front" is wrong. (I think). Check it out somebody.

You're killing me. :-)
The clam shell doors are one of my favorite parts. To each their own.
Thanks
