A 12-leaf heavy front spring A-5310-B has been released for service. This spring is for use on Model “A” cars in sections where there are exceptionally rough roads and cars are subjected to unusually ·severe service.
A new length tie bolt and spring clip are required with this spring (see Fig. 1020). The symbol number of the clamp used, is A-5330-B. It is the same clamp that is now supplied for repairs on the 1928-29 truck front spring.
