Just read a bit about the 2021 NASCAR new cars and boy there are going to be lots of surplus NASCAR parts available next year! Basically everything that they run today, except the engines, will be gone! So lots of high tech 4 speeds and gear sets, $10,000 9 inch gears and carriers, 15 inch wheels, and complete cars if you like them. If you happen to be a NASCAR fan next year is going to be extremely interesting!
