It is a full heelboard panel and not just the ends.
Trying to fit this new heel board. Just put it in and fits perfict with the floor panel edges and sills when clampped up. But when I offer up subframe none of the bolts will line up on heel board. I bolted up to boot floor first tight just to see how things would line up. But heel all seem out between 5mm-7mm.
Should the holes be even from side to side. Could loosen the bootfloor bolts and then force heel board end to fit and tighten all up but would that not mean the subframe would be squint and cause tyre wear.
I have now taken better pics.
You will see from the pics that from side to side that the driver side is closer to the folds at the edge where it meets the sill that the pass side. You can see this even better from the pics from the captive nuts at rear.

The bottom hole is 26mm from edge to centre of hole

This side is 20mm from centre of bottom hole to edge.

You can see from this pic that the captive nut panel is close to folds

But on this one its a bit away.
Any help on this would be great as this was a heritage panel so not cheap crap and I have not bored any holes in it yet so if wrong would return it. Maybe all like that they or just this one has slipped through the net.
As said above more worried about the alignment causeing tyre wear etc as subframe would be squint if I just weld in and force the bolts to line up.
Help and advise please!!!
