BigBlock4Speed70 Posted October 25, 2010 Share Posted October 25, 2010 I saw the other day (somewhere on here, but I can't find it) that there is a difference in the factory holes cut in the floor for a 4 speed and an auto on the floor... Is that true? And if it is, what's the difference? My car has a 4 speed in it, and I know it was originally a console car. The hole in the floor is factory. It's about 2- 2 1/2 inches wide and about 6-7 inches long. Was wondering if I could tell if the car was originally a 4 speed by the hole in the floor. Thanks...

kc8oye Posted October 25, 2010 Share Posted October 25, 2010 BIG difference.. the 4 on the floor has an extra hump welded on and a LARGE hole. a floor shift auto just has a small hole about 2" in diameter that the cable and grommet go into. that's definately a 4spd hole. but a pic would be a lot better to say for sure.

BigBlock4Speed70 Posted October 25, 2010 Author Share Posted October 25, 2010 I looked up the shifter boot and the ring on ebay, and its a match to the hole in the floor. I'm beginning to think this car is really an original 4 speed. http://cgi.ebay.com/68-69-70-71-72-CHEVE...=item43a23646ef Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted October 25, 2010 Share Posted October 25, 2010 Is the shifter mounted to the crossmember or the trans? Quote Link to comment Share on other sites More sharing options...
RichG Posted October 25, 2010 Share Posted October 25, 2010 The hump is also different for a 4 speed without a console. That hump is very "square" as opposed to the rectangular hole with a console. Quote Link to comment Share on other sites More sharing options...
MCfan Posted October 26, 2010 Share Posted October 26, 2010 That shifter boot hold down flange is exactly like mine except the stock version is painted black. I replaced the rubber shifter boot a couple months ago and I am certain that flange is the same shape and size. My '70 is a factory 4-speed with console but I don't know if the floor cutout is the same for all console cars. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted October 27, 2010 Share Posted October 27, 2010 my hole cut in the floor from the factory looks like they hacked it out with a torch Quote Link to comment Share on other sites More sharing options...
kc8oye Posted October 27, 2010 Share Posted October 27, 2010 that's the way they were done at the factory sam. then the extra hump was spot welded in over them. Quote Link to comment Share on other sites More sharing options...
