postal jeep question

maybe this could be applied to any car with leaf springs
there is this jeep for sale and im interested.. in the description it says that it might need a left leaf spring..
if in the case that i do get that vehicle is it possible to change, use, one from another vehicle?

i guess what im saying is that are the leaf springs interchangeable with vehicles..
what do i need to look for?
lenght, widht? thickness? or.....

its a postal jeep.. 81dj5

gracias

As long as it's not the main carrier spring and the spring width is the same should work out ok. pretty ez. I have swapped whole leaf springs and pearches off newer trucks to older trucks, just due to the difficulty finding good pearches, shackles, ect... thats a bigger job. A thicker spring means a stiffer ride, 3/4 1 ton. Hope this helps.

A DJ5 uses the same springs as the CJ does. DJ just denotes right hand drive postal body.
