trike's and trike parts

[Robert Harris <bob@fastlink.com.au>]

I need to know if any one has rail trikes or rail trike parts that they
don't need.

In particular I need to obtain springs for fairmont trike engines as
listed below:
1    lock spring part no A646
2    spring (check valve - 1-5/16" free length) part no EZ456
3    spring (air valve - 1" free length) part no A1361

or if any one could advise me on the specs of above springs or where I
can find them it would be a great help.
