    Will a 73 GS rear end fit under a 70 skylark?

    I think it will require modifications to at least the shock mounts and or spring perches

    Now I believe the inside guts.....aka carrier and gears will swap over to a 71/72 if it's an 8.5

    I think I know where 2 71-72 8.5 rears are and since everything seems to be hard to find for the 70 I will probably go that route.

    If using the 8.5 see if you can save the axle bearings...If they are original... save yourself some leak headaches. :(

    A9 Set9 system has been a real headache for the past 10 years....
