This is a Mk 1 prototype - one of two made so far for testing - by Allard Equipped.
Casting patterns have been modified slightly and 20 more are being cast right now in heat treated LM25 alloy.
As far as I know they'll be around £285 + including mounting hardware, gaskets, & cable clamp and can be supplied with fuel rail mounts for 2WD or 4WD
The standard finish is vapour blast aluminium but, obviously, can be supplied in polished or satin finish aluminium, or powder coated any colour in gloss, satin, or matt.
