No need to turn it on its side. Just run a Speco thomas floor shift. You can also use the shifter from an M20 or M21 four speed box but you have to fabricate a mounting bracket to bolt it up to the gearbox mount bolts and i think you have to cut off the reverse lever at the bottom of the shifter. I ran a four speed shifter on my HQ when i had it, but this was over 20 years ago so i cant remember exactly how i did it. Impala used to make a floor shift for the three speed box back in the day too.

Thanks for all the replys,sorry,its kinda hard to explane,
but there picture in the link below is what I dont want.



Going by the picture,I want to turn the gearbox so the the shifter where the linkages go to in the picture are at the top and am after a unit that will bolt straight onto of it so there are no linkages needed like in the picture,

Hope that make sense, please let me know if anyone knows of any unit that will do this.

Thanks

You should think about talking to somebody with engineering knowledge
At least they could point out any potential dramas
Have a look in Yellow Pages or try a google search on you PC

Why not ask around speedway circles and see if any body has done it
My 2 cents worth not much help i know

You will run into trouble laying the box on its side. Firstly the oil will run out the breather. Secondly the oil filler plug will be on the bottom so you will have to guess how much oil to put in and risk seizing it up if oil isnt getting into everything it should. Then there is a problem with your gearbox mount being on the drivers side instead of being on the bottom so you will have to make a custom mount and i am not sure if the gearbox will bolt up to the bellhousing if you turn the gearbox 90 degrees.
It will be a lot cheaper and easier to just put a floor shift in it.

thanks

I'v asked alot of the stockcar drivers and there have been running them on the side for years now with no problems at all and they run a 51 ford prefect shifter which bolts on,but there are very little 51 ford prefects around anymore and am having alot of trouble finding one,thats why I was wondering if there is anything else.

I cant run the standard floor shifter with the linkages becouse of the hits the cars get they break or bend and have touble shiffing, with the setup with the ford prefect it has been a very good sucsess.
