So, I finished the upgrade and everything looks pretty nice. I had to get some extra bolts for mounting the shocks but everything else seems to be just fine. I wasn't able to get the tiebar on though. How important will it be to have it on there? If I really needed to, I could grind down the two points on the stock blukhead and then use the tiebar as part of the spacer I need to take up the extra space the rear RPM arms take. I would have to drill out the tiebar just a bit as well. Any ideas on if the tiebar is really necessary?
