The title says it all. Is their any way to find out if the car has always been a 4 speed? Thanks in advance for your help!:beers:

Theory has it the floor cutout for the shifter, '68 is rolled or 'die cut', where '69 seems to be torch/sawsall cut.

Another clue is the Trim Tag list of options and looking those up at www.camaros.org

My clue is the upper clutch rod hole in the firewall. Manuals would have a boot in the hole. Autos would have a plate secured by two screws. No self-tapping threads on these two holes would indicate to me a manual trans car.

As Ev noted, the OE 67-68 floor shift tunnel opening for the shifter is stamped, with smooth edges and rounded corners, and has a reinforcing ring welded to the underside. So if your shifter hole looks like the pic I have posted in Post #13 of this thread, the car was at least an OE floor shift manual trans car: http://www.camaros.net/forums/showthread.php?t=67434&highlight=shifter+hole

A 68 will not have any information on the trim tag to ID a 4-speed car, just build date and interior/exterior trim information.

The frame side pivot bracket for the clutch pedal bellcrank (aka Z-bar) will be fastened with short, self-tapping bolts as OE. I can't find a pic of these bolts, but they are fairly unique and different looking, with a short, deep "gouge" in the end threads to cut into the non-tapped/threaded holes in the driver side subframe rail.

A car that was originally equipped with a Muncie 4-speed would have the OE stamped/punched speedo cable hole under the wiper motor, with OE clips screwed to the firewall tunnel opening and down the passenger side of the tunnel to secure the speedo cable running to the passenger side of the tailshaft housing. A car that had a Saginaw used the "standard" speedo cable location near the fuse box.

If the car has an original radiator with stamped codes on the end tanks and/or the application tag, that can also provide clues. If the original radiator has a built in trans cooler, the car was originally an auto trans car.

67-68 manual trans cars also have a connector on the firewall under the wiper motor where the reverse light wiring plugs in. I can find pics on here of what the OE connector looks like if you need them, but if the car does not have a connector, or at least the factory punched/stamped hole for the connector, it was an auto car.

So, check the car over and tell us if you have any of these clues, and we may be able to help more.

Geez, my car was butchered before I got it back in the early '80's b/c I don't have any back-up light wiring stuff now?

Same M-20 tho and Muncie shifter.

Thank you for your help. I will do some checking with this information and get back to you to let you know what I found.

Is there a partial VIN on the trans case?
