Suit restoration enthusiast. I am not able to finish it

Much of the interior has been replaced:
knee bolsters
front seats
door trims
I/R remote entry
Steering wheel
Instrument panel. (digital, all works)

New brake pads, new battery, 80% tread on tires, original spare (new condition) all chrome work still like new (no blemishes or flaking)

Runs and drives (not currently registered)
engine needs attention, not sure what....
Starts first turn of the key, idles erratically for the first couple of minutes and then settles to a nice idle.
Slight rattle noise I think is coming from the manifold cover plate.
Original booster brake system (not working) so brakes are not assisted. I intended to replace with vacuum booster.
Rust across back window.
