The MGA With An Attitude
Factory Option Codes for the MGA Twin Cam - TC-114

Twin Cam production information (2111 cars) including option codes was hand copied from the factory production record books just prior to the factory closing and skipping all their records in 1981 by Phil Richer over several days. This information was then compiled into what ultimately became known as the "Yellow Book", which then has been refined and became the Dutch online database (Koen and Jerry).

In general, this option list may also apply to the "Deluxe" cars which share the Twin Cam chassis (except possibly the "Engine" option that may be unique to Twin Cam). Options for the "Deluxe" cars may also include a few things for the pushrod engines, like alloy valve cover for instance.

CODE NAME 455Ax 4.556 rear Axle ratio -- perhaps 8% of all TC cars 4.875Ax 4.875 rear Axle ratio -- so far only 2 recorded Ae Aerial -- a few recorded, presume this is a stand-alone part when radio is NOT ordered) AlSWh Alloy Special Wheel ? -- (none recorded so far), may be the very rare but well known pin drive aluminum wheels. AnSh Andre Shock Absorber -- several of these recorded ARBr Anti-Roll Bar -- only a few of these recorded, (apparently originally rare on Twin Cam, most TC were 1500 style with no mounting for the ARBr until June 1959) AS Adjustable Steering (column) -- a couple dozen far, maybe only 1% of all TC cars (far below the average for other MGA) ASWh Alloy Steering Wheel - about 6% to 7% of TC cars AT Ash Tray -- over 100 recorded (about 5% of Twin Cams) BB Badge Bar -- a couple dozen recorded BC or BATT.CVR Individual Battery Covers -- several recorded Bmpr Bumper -- one recorded as "less FtORdr&RrBmpr" Bkt Bracket (fog lamp) -- only a couple recorded as "2FLtBkt" CAP Unknown description -- couple dozen cases recorded, (anyone want to venture a guess? perhaps same as COP?)
