9 inch rear end install help

[jhall4679]

I'm trying to install a Coleman 9 inch floater in a 1984 monte carlo chassis. The rear end had been under a g-body car as well, but when I go to connect the upper trailing arms, I'm off by 3 inches. The stock upper trailing arms are just over 11 inches. Do I need longer trailing arms or what am I doing wrong?

you have to jack it up into place you cant bolt on the uppers with the rear end hanging

I have it jacked up with jack stands on each side supporting it. The problem I'm having is the spread of the upper trailing arms being too wide.

then it must not have been in a metric car before?
