Jams, I would give you the # if I could but I built my own coilovers, I got hd shocks for 89 mustang rear, from autozone, about $23 each, 200# springs for $49.95 ea. and coilover kits for about $41.00 ea. Springs and coiloverkits come from speedway motors. web site

My rearend is not like anyother in a B&B, it is a shorten chev with 3 link hookup.
