Thread: MII cross member advice on my frame

Tweet

Guys, I've decided I'm going to replace the hacked in MII stock cross member in my frame with a new fabricated style. This sounds pretty straight forward. However, I'm concerned that by the time I get the old one cut out, I'll find that whom ever installed it more than likely hacked up the frame pretty well too. So, I'm trying to decide if I would be better off purchasing a bolt in cross member or weld in one. I'm leaning towards a bolt in for a couple reasons. One, there will be more material to work with on it due to the sleeve that goes inside the frame rail. Two, I can bolt it on the frame and then repair my frame and have the correct geometry with out any guess work. My biggest concern with using a weld in style is that it's going to take a lot of work to get the frame rails fixed to get the correct geometry and have the joint be strong. Since I'll have a heavy engine and plan to add a supercharger later, I want it strong from the begining.

According to Speedway, their bolt in cross member is stronger than a weld in unit. It is also set up to be used without strud rods which is the style of control arms I have. So what are your guys's opinions on this? Here are some pics of my front cross member now.
