Cheers bud,..When your forwarding drawings (basic in my case ! lol) , specifications, sizes,etc,.....its easy to miss the odd detail out,...(as i did) lol Also , im not that 'technical', so cause i wasnt that familiar, i left it up to those who made them, as far as how long the 'sockets' where ? how they where attached, etc,.....but overall, they are definately 'fit for purpose', (in my opinion) but im certainly not going to claim, they are 'perfect',....lol Both, are well made and durable, though.
