Outer Limits 4x4 Board

hey guy's , I just put new springs on the stripped down MK chassis, with no weight on the chassis the rear shakles are pulled all the way forward, having only owned the car for 1 day before stripping it down, i didn't see the angle of the shakles before the body came off. the new springs (westcoast suspension) are the same length as the old ones, just with a bigger arc, so getting them in was a bastard, cause they took some thinking to get them into the shakles, cause the shakles are up against the chassis( see before sandblasting and painting pic attatched). the guy's at westcoast suspension said that when the weight of the vehicle back on the shakles will pull back a bit, he then said that I may have to stick a pinch bar in there and laver the shacle back to the rear, the question i have is, has anyone else had this happen to them???
