Hi,

If you go to Dreamworks home page, it will give you an idea of the size. If you buy the Pro Link retract system complete which is designed for the Sprint, the cost is $825.00 complete with everything including both air tanks. You can order right from him or Patricia @ boomerang, USA in Texas. Shipping is only $10.00. The system is great and has been designed so you DON'T need to use any shims under the retracts. The fit is really great and the quality is super.
The system has everything you will need including both air gauges..Go check it out...
