Take a photo of the side where the hoodlining would attach, there is a wider metal strip welded along these for attaching the pinchweld.... there should also be holes visible where the hood bows attached.

There were plenty of V8 4sp bucket seat with full headlining vans ordered for tradesman and as other work vehicles..... a lot of companies or tradies wanted V8 power and better comfort without the lairy GTS fluted guards, rally sports wheels and stripes.
