'90 Mondiale "T" wheels replace with stock 355 wheels

Threads similar to this have been around before but never answered exactly! Can I replace my stock '90 Mondiale "T" wheels with stock 355 wheels and when I do, exactly what spacers are needed [if at all] and do I use the same wheel lugs that come with the 355 wheels and what size tires should I use.. I have retired the car from track events and use it for weekend trips.. I would like better handling and a quieter ride.
Sorry if this is redundent but I never got a straight answer.
Does anyone have a set of 4 "as new" 355 wheels for sale?
