First of all I don't think that site is very accurate. You are looking for part numbers 20311PA001 and 20311PA011. No one has the old style struts for sale unless they are New Old Stock (they were ordered before Subaru stopped making them and have been sitting on a shelf for 14 years). Subaru stopped making them years ago. That's why you had to replace both struts if you had the older style.....your Suby dealer couldn't order one of the older struts and you couldn't mix 1 new style with 1 old style!

These struts from the dealer run about $130.00 each.

The -29 and 2X- are two digit production codes.

The -29 means "up to and through the ninth month of 92". The first digit is the last number of the year (1992) and the second digit is the month of production (9 is September). In this case it is not 100% accurate because the actual Subaru bulletin states that the strut change happened 10/10/92, but its close enough.

The 2x- means "starting in the 10th month of 92 (October) and continuing on". Again the first digit is the last number of the year (1992) and in this case the letter X is used for 10 because Subaru wanted to stick to its two-digit format (210 is three digits, so X was substituted for 10). Again, not 100% accurate because some cars built in early October 1992 had the old style struts, but you get the picture.
