Thinking about ordering one online and I want to make sure I get the Gen 2 whipple. Any suggestions?

 

I'd email Whipple directly...they could tell you...

Another question...Do they even sell Gen I's anymore?

 

I seem to recall there is a difference between the serial numbersm, what the differences are ????. I do know that the HO Gen II ships with a 3.5 pulley. The Gen IIs have been shipping since at least early April so unless the kit had been sitting on a shelf for some time it would be difficult not to get a Gen II.
