I haven't welded in about a year so I practiced a little bit on this. All I have to work with is a little Chicago electric flux core welder, The poor little thing only has a 20% duty cycle when I set it hot enough to weld anything this thick.
its hard to tell but maybe u can weld the sliders/brackets from the old seats to the new one
The widths at the sliders are a little bit off(about an inch and a half I think I measured), and I would hate to mess up the new seats while cutting on them, my welding is REALLY rusty and I would probably just burn right through them
. I didn't pay much for them but I would hate to have to dig long enough to find another set of used seats this clean.
... But I haven't put that much work into brackets, come morning I will probably look into if I can make this work.
Either that of weld plates to the bottom of the mounts on the new seats and drill new holes that line up.
I had thought about that first, but with the front mounts so far forward, that wouldn't want to twist the stock front seat mounts?
