BELLTECH DROP SPINDLES FIT A S-10 HELP?????

I want spindles for a 1998 s-10 and I found these but the guy that is selling them does not know what they fit. They have the number 31200 on them. You can see more in the pics. If any one can tell me what they fit it would really help me!! http://i15.ebayimg.com/01/i/03/76/f3/27_1_b.JPGhttp://i18.ebayimg.com/03/i/03/76/7d/65_1_b.JPGhttp://i6.ebayimg.com/01/i/03/76/ea/63_1_b.JPG
