Diff mounting plates and seat mounts.

[David_17]

As some of you may know, my welder is running off a generator, as my lockup doesn't have electric.

Sadly, it isn't quite powerful enough to weld 5mm plate, the engine just dies. For the diff brackets this isn't a problem, as i can take them home and do them off the mains. But the plates on the chassis (that the diff brackets bolt to) i'll struggle with.

Would i get away with using 3mm plate? Or have i got any other options that people can come up with?


Also, my seats will be bolted to 25mm box section (2mm wall), would the iva man prefer if i bolted right through the box section, or drilled a hole bigger than the bolt head on one side of the box, then bolted it through the hole (if that makes sense)
