Hello,

In a previous post I asked for opinions on whether I should get a lock-up or non-lockup A904 for my '73 Duster project - thanks to all who responded.

In the meantime, it was suggested to me that instead of getting a late model A999/998 to take advantage of its 2.71 low gear ratio, I should instead rebuild an earlier A904 with the low gear set.

I will be using a mildly built 5.2L Magnum and an 8 1/4" rear end with a 2.45 ratio.

Any thoughts?
