I used a Vintage Air Mini II unit. Fit just fine although my motor is a mid-70's 250. I only had to trim a bracket a little bit, other than that, everything was bolt-on and the kit was totally complete, pulleys, idlers, brackets, hoses, controls, blower etc. I did have to buy an electric fan but that was needed anyway. And I did price out buying pieces and assembling but it was roughly the same and not worth doing.
