Coil spring isolator question!

So I'm installing a 2" BB soon and I ordered two different isolators (NOT spacer) the fronts are MOOG from RockAuto and I got the rears from IRO. The thing is, the MOOG ones are 4" in diameter and the IRO ones are around 3.75" diameter. If you place the two on a spacer, the MOOG one fully covers the spacer when the IRO one doesn't. Eyeballing it, it doesn't look like the IRO ones would fit.

I just want to know if this is a big issue or not? Should I just order 2 more MOOG isolators and throw them on the rear? I only have 3 days before the lift starts.

Side note, the spacers are from RE, all 4 of them are completely round. The front isolators are round, the rears are D shaped.

I have used the IRO coil spring isolates on my 2" bb and they are factory replacements. I bought the front and back from them and they do work. You are correct the fronts are round and the rears are d-shaped. I put the isolators on first and then the 2" spacers.

Ok that gives me more confidence but why would the 2" spacer be a bigger diameter than the isolator?

I'm really not sure if it was bigger or not. I think it might have been actually. I don't know why it is bigger, maybe to give it more strength.

Mine isolators are 0.25" smaller than the spacer in the rear. Hope these work. Thanks for the replies! Now I gotta figure out how I'm going to pound my 2" exhaust extension in the isolator haha.

If my isolators are worn should I replace them?

Honestly I would...Mine are so bad that the rubber is all torn up and the metal plate inside its exposed and rusted to heck. Just poking at it made chunks fall off I live in Wisconsin so it sees salt.
