I have had & currently have a streetrod w/a Must II IFS. It does not drive
as well as some of the other front ends.
There are kits that use GM components from a g body car that drive better.
I was one of the first to use theses front ends back in th 70's before kits were avialable
& they are much better than the buggy springs I replaced on early Fords,
but imho, not better than 70-80's mid size GM front end components.
