To help this guy along..really speaking...it isnt worth doing, unless you can get a cracking deal on the bits you want.
The body will cost you, if you get it from Punishers, around £80 shipped (they do have other colours than black, most have soleoid inserts allready.
Then you need a grip, which could cost between £20 for a secondhand stock one, to £70 for a CCM or TonTon frame.
You need a bolt kit £70 ish, manifold, screw/pin kit, eye, eye cover, solenoid £90-120, lower board £25 -£85 depending what you want, front mount, feedneck, vert regulator, bottom line, grips etc...if you can source them secondhand or trade for stuff, great...but, you can buy a shocker for £235..so..
