To answer Dick61, unless they changed the rear quarters to WB it's a WB shell, I've removed the panels in the tray and there's no evidence of the panels being welded. Thanks for the info on the seat holes and firewall loom positions. I also have a HJ, a HZ and HX so I can compare with those. Now that we're pretty much certain it's not a Sandman or anything special, am I still able to start a rebuild thread as it progresses? Plans are an LS1 and big tyres, it won't be a Sandman lookalike.

I'll post some pics when I work out how
