When I went to the race car show at excel in Jan I picked up a leaflet for this firm. They put splines on driveshafts, cold drawn.
I will be using them to put a Rover spline one end and a lobro on the other.
Just thought it might help some of you guys out:
Track and Rally

have you contacted them?

I asked for a quote to make a drive shaft for my de-dion. GB Engineering wants about a 90pounds per shaft. These are the ones that lots of grassers use and are of a known good quality.

Track and Rally wanted £176 per shaft! GB do gun drilled 'unbreakable' shafts for less!

No I haven't got my quote back yet !

You were right, £174 each plus £50 to have them drilled !!!!!!!!!!!
Have you got gb engineerings contact details handy?

Cheers Martin

errm......
not handy,

search on here for GB engineering or google, they are based in Nantwich. NS Dev often reconmends them (they do LOTS of grass track drive shafts).
