99 switch

[steveof250]

what date did the 99 change the turbo wheel

[jphelzer]

My understanding is that 12/98 and earlier are 99s and 1/99 and later are 99.5s.

Somebody smarter than me will correct me if I'm wrong!

[99 7.3]

i'm by no means smarter, but from what i gather, the early 99's have the wheel.

You should be able to look at it and see if it has alternating different sized blades(good), or all the same.
