I have an ifs (M ll design) on my 46 chevy truck. Not sure who made it or installed it but my truck likes it. I am in the process of doing a rebuild on it but other than just worn, I like it.

Dave has some experience with Speedway so thats good. I kind of dont trust some of thier stuff. I have read some things about parts breaking. I would assume they are being made off shore to make it cheap. Just look things over and replace or repair anything that looks shakey (at least thats what I would do)
