Hey Guys,

You have done the drive axles on our race cars in past years, and I wanted to thank you again! The competition at Michigan International Speedway in May went great this year, we placed 90th out of 120. We were happy  with that since we had barely made it through safety/tech inspections and weren't able to compete in some of  the dynamic performance events due to multiple failures including our brake light mount, shifter cable, and  clutch master cylinder.

We are designing a new car for 2014 for competition in Lincoln, Nebraska in June. We have just gotten started  on building the welding jigs for the frame. This car will be using a Yamaha Phazer 500 snowmobile engine  with CVT transmission. A secondary shaft will still be needed between the CVT belt and the chain-drive final  transmission to the drive axles. This secondary shaft will be consisting of two ends of splined shafts, one for  the CVT clutch spline and one for the sprocket spline. I figure mating these two shafts and keeping them true  will be no different than what you've been able to do for our drive axles in the past. I was hoping you guys  would be able perform this service for us at some point this semester before Christmas.

I will be making contact with you again once the two shafts have been designed and are nearing being ready  for mating.

I look forward to working with Driveline Specialists again. I've attached some photos of the finished car for  your viewing pleasure.

Thanks again,
