With 600 BHP per ton - I would get special one piece shafts made

Try GB Engineering.

I used a company in downham market years and years ago to make some drive shafts for me for a nova (i know!) which i fitted a redtop in. This was before the likes of courtney even thought about it. Im think they were called carquip or something like that. I took them my old shafts and said same again but shorter, and there they were!

was along time ago tho'

Look in any kit car mag or PPC. There are always people advertising for custom made driveshafts.

This was discussed on Retro-Rides this week, worth a look?

I go belt and braces on mine, my method is to cut the shaft in half, then turn down one piece by the amount that I wish to shorten it by, bore the opposite piece to suit, cross drill and weld them, fully weld round the V'd out join, then sleeve it

this is my home method of shortening them and keeping them straight, never failed me yet

although I never had serious amounts of power through them, but I was taught to do them this way years back by a guy that built big yank engined things, he built drag cars for a living and at one point owned the most powerful street legal road car in europe, so I kinda took his advice.

all depends on the budget, if you can afford one off or custom shafts, then go for it, me I cant so do them myself

Angle grinder.
Did you want to use them after too?

I think the trick is not to cut and join but to cut to the required length and then machine the hub end of the shaft to suit. This will be at least as strong as the original shaft.
