Help locating steering column parts for '57 MGA

["Pleczko, Rick" <Rick.Pleczko@MissionCritical.com>]

I am looking for a couple of steering column (shaft and key)  parts for a
'57 MGA. The Moss catalog marks the shaft as NA.

I would be grateful if anyone could give me an idea where I could find the
shaft. I would prefer NOS items but a good used part would suffice. The Moss
catalog details of the parts are:

Page 23, item numbers 63 and 64 Moss part #'s 263-070 and 327-080.

Thanks for you help
