Making Classics Trypticon UPDATED 28/08/2011

First of a big thanks to Chibbywave for making this custom in the first place. This is were i got the idea from if people are unsure
http://www.seibertron.com/energonpub/classics-trypticon-it-walks-t78463.php
im basically looking at copying this design but changing 1 or 2 things to it possibly
At the moment this is still a WIP which is obvious by the pictures. The main body has been repainted but i need to touch up afew parts and respray 2 other pieces i only just noticed
im kinda stuck now however as im not sure what parts were used to make the spines/spikes rotate 90 degrees. I asked chibby himself but aside from giving me the obvious of 'its alot of work' and simply 'lego parts' he never actually said WHAT lego parts. Ive no idea what there called or how to find them because..well i dunno what there called..ssoo any help on that would be great
im still working out how to attach the 2 shoulder cannons which is proving to be more difficult than what i was originally expecting
either way im gona keep this updated till hes eventually finished and before anything thinks doing this is easy...trust me its not
oh i ment to ask, if anyone recognises were the RAMPS come from that would also be alot of help
