Rebuilding Stock Gearbox (Upgrade suggestions)

[Goldie_7]

Got two spare gearboxes, one is in working order which I\'m keeping as a  spare for a straight swap and the other has a crunchy 5th.

I\'m looking to rebuild it completely when I have time to both learn how to strip one and improve performance.

I\'d ideally like to convert it to dog engagement for quicker shifts and  maybe throw in straight cut gears although that\'s optional depending on  others experiences with the noise! It\'s mainly tracked although  perfectly road legal.
I\'d also like to give one of those Ikeya sequential converter shifters a  go too and see what it is some have been struggling with when setting  it up.

So any info welcome on where to get good deals on kits, etc.

And if anyone has anything they could sell that would help, would be much appreciated.

Time\'s no issue as it\'s just a side project.
