I just bought an almost completely restored 1975 pickup which is a RHD HJ but with a recon 2F motor fitted. I wish to complete the restore as much as parts are available. One area that needs attention is the dash, no heater or ac, and there are only 3 knobs on the dash however several empty holes. Need help identifying what those were for, if anything. If anyone can help please advice. There is a working light switch and a wiper switch but thats all. I also want to install a dash pad - is there a difference between the dash pads for left vs. RHD? Will also search to see if anyone on the forum had done a heater installation for the RHD, with instructions, because I will need to figure out what all parts I'll need and how to do this. Cheers.
