how does the crossmember bolt up on the bottom or top of the brackets. how long of bolts do you need. thanks
If your talking about a 80's Regal the cross member bolts on the top of the brackets and a bolt 1 3/4" will work just fine.
If your cross member came with the bushings they should be fine to use again. Both my Regals have after market cross members (G-force) so I don't use the bushings.
