[QUOTE="Chris Stephens, post: 1485135, member: 24095"] Got some small things done today. Test fitted everything and got the accessories mounted. I really like the low-mount alternator bracket. Looks killer. I wish the guy who makes this would finish the power steering bracket so I can get rid of the ugly bracket on the other side. [ATTACH=full]10362[/ATTACH] [ATTACH=full]10360[/ATTACH] [ATTACH=full]10359[/ATTACH] [ATTACH=full]10358[/ATTACH] We had a problem on the dyno that took a little figuring out.
