The bar beneath the seat that adjusts the forward /backwards motion has snapped right where it connects to the toothed cog. ( on the outside edge under the seat). Is there anyway to weld this other than to replace the whole thing. The dealership near me wants 450 for the part and 150 labor. Right now that is not feasible for me and the seat rocks to the front outside and I dont want anything else breaking due to this. Thanks for any help!
