    Are you looking for the eye to eye length of just the main leaf when it is un***embled? Full spring pack ***embled and off the car? I have a main leaf laying on my garage floor right now so I can measure that for you when I get home from work.

    Use a 'T'. Flatter and prettier, holds its end-to-end dimensions. But 2" leaves' width, opposed to the 'A's 2.25".

    T 44 1/2 inch. A 45 1/2 inch. They can be off a 1/4 either way depending on sag/use over the years. They interchange width wise, as mentioned the T lowers the rear 2 inch and its a 1/4 inch narrower width where it bolts into the cross member.

    I'm getting ready to locate mine. I was told the dimensions were 48-1/2" or 49". I was putting mine at 48-1/2". I hope that's right.

    Try this....

    Seems to be 49.5" keeps coming up and it's the number I remember. I measured mine because I duplicated that dimmension on a stronger rear axle. Turned out, I couldn't get the car low enough, so I s****ped that idea and went to coil-overs. I still have the brand new spring and it's still for sale.:D

    Apparently Posies recommends 48.5" - their spring must be softer? I'm 99% positive stock is 49.5"

    Yea thats the reason im asking...I have removed 4 leafs and reversed eyes on my A springs but would like to get another inch or so lower if I can. Just wondering if a T spring would make that extra inch

    You can rearch the A spring, I got 3" rearching mine with a pipe bender.Next time I will reverse the eyes as well. You can use a press too, whatever you have or can borrow. Put more arch up near the top and flatten it further down, like a T spring is.
