Well lots going on but back to the task in hand, its been played with here and there and some parts have to be removed in a more aggressive manner than i would prefer but result is the same...
seems they got carried away with the spotting

so

i did unpick the 4 spots here, been as easy to chop it off and remake but a line to be drawn someplace

ive opened the rear arm area up , its not terminal but needs the usual,

straight edge to cut the crappy bit out

in fact quite a bit cut out

no point leaving this sort of stuff here as its never going to be easier to do now

first part made to fit here,in the same gauge as OE.

likewise with a new load bed edge to form the closure
