ah - i didnt realise u were going for the telescopic/sliding setup mate...

im only using the male part with a small part of the female shaft to hold the pin, that secures the cen shaft, in place. i didnt go for the whole fancy telescoping setup due to having no chance of the female shafts clearing my shocks. i suppose i could have a slightly longer female piece, and have some telesoping/sliding shafts, but just the male section has held up well enough for me tbh, and it allows clearance of my shocks.
