[TR] set available, NA individual

[dorpaul]

 I am about to order a brake pipe set for my TR3A from Moss or TRF.  Of
course, it contains more than half-a-dozen individual 'lines' or 'pipes'.  The
entire set is available for  about $124.  However, many of the individual
pieces are NA.  Why is this?  Any preference for venders?

Thanks, Paul Dorsey  60 TR3
