Thanks hk. Just bouncing ideas around.
The engine idea was mainly for the sandman panelvan I got as the rails are original to the body on it, i know how unlikely it is that ill find anything close to the build date but I got access to a few 308s. Was gonna grab the numbers off them an try my luck.
I know the ute will never be what it used to be, im sure there will be people that can apreciate it for what it is now, even if its not original.
