Well, I won't tack this on to the Onstar thread since they seem to get poofed and when I am actually able to say something intelligent I hate to see it goe to waste, My issue is not with On star but parts support. Many years ago I was given GM front spindles and traded for another pair. Used them to make axles for a homemade cattle trailer. Didn't use good enough pipe in one axle and have had to redo it after about 25 years. Naturally went to repack the bearings. Advance auto was able to track down 2 grease seals for the spindles that probably came from a chevelle. The other spindles probably came from an Impala and since I don't remember the year model I wound up going to a bearing and seal place, with measurements, and the seals are due to get here in a day or two. Now, my compliant about GM is that the parts guy said they only kept those parts back to 1977 and I think the spindles came from a 60s or early 70s model. I wonder what the guys restoring classic cars do about some of their parts requirements.
