Haven't had time to look at changes underneath, but at the front is a Holden radiator with shroud and it's done so well it looks like it's original. There's about a 2" cut through the firewall behind the engine and a modified trans tunnel, also well done. Some finishing off work to be done in this area, but only because I'm fussy, quite serviceable as it is. Will post more pictures of the conversion when I get into it.
