A Lazer spur is way too big, put one on a Mid and you'd never get the motor in.
The Mid uses a 75T 0.6 mod spur gear. One option is to get a 48 dp spur around 80 tooth and ream the hole out slightly so you can use a 4x8mm bearing. A better alternative is to contact RW Racing as they made 48dp alternatives back then.
