Would anyone know where I can buy a mainshaft for my swing axle gearbox? Are there any stronger ones available?

Michael the best solution would be to spring for an Albins first and second set.
By the looks of your photo you have the weakest (narrow faced) 40hp first gear available.
The '67 aussie bugs had a better/wider version, but still with a nut on the end of the main shaft like yours.
Later still had the same strength, but circlipped end.
The L-Bug, or 1800 bus, does use a slightly better first gear,
so this is a good upgrade, if you ise long roller'ed needles, and keep end float at minimum spec.
.... but the way I see it is,
if you can break that one, you probably want something afermarket.
As Mac says above, have a close look at what clutch you are using.
It is easier to fix a slipping clutch than a main shaft,
and what ever parts the schrapnel has hit.

Dave
thanks for your input, when you say 67 Beetle is that 6volt or the 68 12volt 1500 transmission. would you have a part number so I'm not stripping gearbox after gearbox to find the bits. I have broken 2 of these units in 5 years of racing this car and always when I got a bit carried away (the dreaded red mist) I actually am running an adjustable slipping clutch but both times I've forgotten to turn it on. The trouble down here in Melbourne is we just don't get the events to put in the practice.

Michael, the gears I speak of with the threaded end, are before the '68 12 Volt one (just).
They have the same tooth count as what you were running, but are a tad wider.
Look for swingaxle gearboxes with a seal on the shift rod,
and a plug in the reverse light switch position in the nose cone.
There will be a stamped number on the underside of the case(like an engine number).
AC or AO prefi will have the circlipped end and are a 12 volt case,
where as the earlier cases will be a eries of numbers with no letter prefix.
