Probably a daft question, but my motor is elsewhere as I sort a replacement tub out.

I'm swapping the supports with replacements, is moving these back/ forward a few cm to fix into new fixing holes critical to the fit to the chassis?

Cheers

HI
the 3 floor supports sit on flat areas with rubber pads on so will still need to sit on those so cant move too far, is the floor holes corroded away, easy enough to put a new floor in
