Rear shock question???

just completed the swap yesterday and the old shocks fit perfectly. you will need to keep the original e-brake cables too they fit right into the 8 3/4. and driveshaft will need to be shortened. i used a 70 coronet driveshaft which fit perfectly with the 904 to 7 1/4 combo but had to take about three inches out to fit the 8 3/4.
