hey guys, does anyone know if the toploaders fitted to 6 cylinders are any different (internally) to those bolted to V8's?. i'm thinking of things like input shaft diameter/splines, ratios, bearings etc, or were they all the same?
cheers,
Phil
As far as I'm aware there are only close ratio toploader's,ie the bullnose and the standard toploader, but genrally a toploader is a toploader, I've never heard of a wide ratio version before?.

A toploader is a toploader. A Cortina sourced toploader is the same unit as used in the Falcons, but was only available in a wide ratio version. The close ratio toploaders were used in the GT's or available by special order in lower spec Falcons.
The shifter on a Cortina sourced toploader is in the wrong position for an X series Falcon so you need to replace it with an aftermarket shifter. It is too far forward by about 6 inches.
Ex-Cortina toploaders are a great idea because the box is not likely to have had much of a work out.
The 'other' type of toploader out there is those sourced from an American car that was behind a big block. These are slightly different - have more splines and a few other goodies though the gear sets are the same.
I thought there was a pseudo toploader hanging around, with only 4 bell housing bolts instead of the 8? i think i read that on an american toploader site though, so it possibly could be different

There is something like over 100 variations of toploaders. Different splines, different lengths, different bellhousing mountings, different shifter mountings, different gear ratios, big block and small block versions.
Close ratio was only Australian available on Phase 2 and 3 GTHO's. They were not optional on anything else. The vast majority of toploaders are wide ratio.
well i must be in the minority cause i have a 4 bolt (dont know what spline) close ratio gearbox. Got it off a wreckers place, came out of another xd. Looks just like any other toploader.
