3rd gen leaf springs fit on 2nd gen?

Hey I just got given third gen leaf springs I was wondering if they would be interchangeable with my second gen stock leaf springs? My old leafs are clapped so hopefully they fit

 

Yup should bolt right up. Make sure to put them on the proper sides.

 

Are factory springs marked for this? If not, how do you tell?

 

Run the part number on the top of the leaf and it will say which is left and right since the part number is different.

 

Cool, didn't think of that but it makes sense.

 

out of curiously, Aside form left and right, are there differences in rear leaf springs between the models? i.e. assuming a 4 leaf pack, is the 2nd gen (or 3rd Gen) access cab rear leaf spring set the same for a Double cab long bed or a standard cab long bed? Thanks
