Mr Cylinder obviously knew when to out that one then.
It's all standard E36 stuff. Two new complete wishbones with the lollipops fitted, two complete steering track rods, a pair of front calipers and pads (just replace both) with flexy hoses, remove and refit the exhaust, repair the trailing arm pocket (often a cunt of a job), tracking and resubmit.
Welding apart, that's a steady weekend or a flat out Saturday.
Parts, about £250-300 all in.

Two calipers: E36 and E46 interchange but make sure you get ones to fit vented discs.

It's clearly a rusty old thing underneath - time to give it the push once MOT'd.
