FMJ suspensions can be rebuilt by most members in here - who have a general set of tools and access to a press.
The only really special tools are:
The upper ball joint socket:

1973-76 Mopar A, 62-79 B, 70-74 E Body, 60-62 Dart Upper Ball Joint Removal Tool | eBay






Do you know the actual size of the ball joint? Can't seem to find the size of the sockets in any of the details.

I have a forum post to create about ball joints – but only 8 months behind on writing it.

1-15/16” (1.9375").

A 2” open end wrench will work but an crescent wrench works best – if you don’t have the socket.

Actually, both work great, together.

Edit: be very careful when screwing in a ball joint, regardless on which tool you use – for it is easy to get one cross-threaded/joint going in at an angle. Take your time for if you get one on at an angle/cross-threaded, then you will not be able to re-use that arm (hole stretched out).

Depending on who you talk to, you "might" be OK by using the arm with a cross-threaded/angled ball joint (my opinion is NO, don't use it) – but it is best to just do it correct the first time.

The ball joint top has 4 square edges with rounded corners, something like this:

My firmfeel leaf springs have sagged out and become dangerous in less than 2000 kms indeed they have cut down a tire. I am so not impressed

Their prices lately have gone up. $550+ for a pair of leaf springs is nuts.

When did they go up so much everywhere?

Really I just want good product. Why is it that the right rear from Mopar is heavier than the left yet from Firm feel they are the same on both sides ? It is my right rear that has sagged at less than 2000 kms

I am very pleased to say that I now have the replacement springs and they look much much better than the first set. They explained to me that the sub contractor that makes the springs for them had a heat treatin issue on mine any how the car sits up very nice now.
