I picked up a 4 speed gearbox to replace my old 3 speed but it seems I could be in strife with the linkages setup.
The selector bit is at the back of the 4 speed whereas it`s at the front on my 3.
Is there a writeup or something on this changeover? Am I going to have to cut a hole back further for the shifter?
Cheers , Bob.

I have a modded 4 spd shifter to fit at the front and changed operation for reverse, It's in the shed some where at the farm.
I took the 4 spd out to fit toyota 5 spd. be up there Tuesday night if I remember could get a pic.

Thanks for the reply ethyl .
I would be interested in the shifter for sure.
I most probably wont be doing the changeover till after summer ( when it runs out of rego ). Hopefully keep the `ol dear runnin till then :) .
At the moment Im working on getting her ready for a paint job.

I posted a reply to a question you asked previously about this (see some of your previous posts) and also I have commented on this very thing before.
"When I bought the 4 speed it came out of a holden one tonner, and I got the box and shifter.
when I installed the gearbox I mounted the shifter in the standard position (bolts straight in) I also used the two three speed linkages for the forward gears (no mods required) and one of the 4 speed linkages for reverse Had to mod it a bit, (cut and bend from memory).
I also had to rebend the reverse selector leaver up a bit to stop it fouling on the bell housing, nothing drastic, and bend the stub that the gear lever sit on forward so that the gear sits forward.
Have a look at my gallery for some pics."
When you get closer to doing it and need more info PM me your number and I can talk you through it.

I fitted the 4sp shifter to my 3sp box today so thats a start eh .
Ethyl , I will have to pass on the shifter you mentioned . Thanks anyway ( hope I haven`t put you to too much trouble ).
I will wait for a rainy day and pull the 4sp apart to make sure it`s ok before I bung it in .

Took the side off my 4 speed (M20) and found these UFO`s inside ??? .
The gears all look fine so am wondering where they came from .
Can anyone recognise them?
Surely someone wouldn`t repair a box and leave these inside!!
I didn`t want to disassemble it but maybe no option :'( .

Postie Bob, I think the file was too big. ;D

Have identified the` mystery bits `.
I recon the tooth is/was part of a reverse gear . The small flat bit of metal was the spring from the anti lash plate under the reverse gear .
The piece with the hole is the end of the circlip holding the rear bearing in place. ( both ends of the circlip are gone >:( ) .
There must have been some major destruction happening in there. The broken circlip is still doing it`s job though .
They say " nothing is impossible " , getting that circlip out now would be very close to the `impossible` .
Whoever repaired the box must have done it on the side of the road ;D .
Anyway , all seems ok now so will swap it over when I get some other projects out of the way.
Cheers `n` Merry Xmas to all.
