I'm new to posting on here but I have been reading this forum for a while and have found it very helpul. I bought a used 03 f5 at the end of last season. It was completely stock. I was working on it today and I noticed a crack in one of the slide rails. Its near the rear, right behind the inside bogie wheels. It starts in a unused bolt hole and extends up to the top of the rail. Is this something that can be welded or do I have to replace the rail? I tried a search for this info but the search engine is shut down right now. Any info would be appreciated.
