hiya…when we built the cabs they sat on a wheeled jig the back panel sat on a channel and a strut held it into place
the door frame located on a plinth that the front bottom sat on claps held the frame to the back panel it all worked easy.
the big problem at jennings there was no room. when we did the 8 wheeler it was worked on in the gangway.
if another job needed to be moved to the paint shop the 8 wheeler would have been pulled out and shunted back when
it was ok. this was quite normal with any job that was mobile. some car repair jobs was done in the gangway/alleyway…
it was about 12 ft wide but not IN the panel shop.
