I have a set of new steering arms used on the 500E/E500 part number
129 332 03 20 and 129 332 04 20 for those doing the 500e brakes on their w124's, might also work on w201's (perhaps someone can confirm). The dealer quoted me $139.89 each. Selling the pair for $100 + shipping

The 201 ones are shorter, you wouldnt want longer ones on a 201. For racing purposes you would want shorter ones for quicker steering. So probably these fit 500E, some SLs, etc. If you had them for sale about a month ago, I could have used them! =(

Thanks for the reply Austin.
