need new leaf spring bushings

[n54power]

Disclaimer -the lift was on my truck when I bought it and I have no clue on the brand. I've been slowly replacing the worn/****ty Parts.
now my front leaf spring bushings are toast. They are poly 2 piece units that came with the kit. I'm going with the idea the lift manufacturer used a spring eyelet that would use a stock bushing.
thoughts?what are the chances that the manufacturer used a spring bushing is for their springs only?

So we knocked out the front springs todAy.
the rear eye bushings were Shot.literally ridding on the metal sleeve.

Front bushings were on their way out.still doing their job but not for long.

For Sizing the front and rear were the same size. The rear eye bushing is used for both.the stock front is much much larger. I got emails back from a few manufacturers and they all state thatbthe bushing for their springs are the same front to back.

So after a few days of driving it's been alot better. I'm still getting a small thud Though. I've read two different torque specs For the main eye Bushing.
185ft lb for both. Other people have said 249ft lb for the front and 190 ft lb for the rear bushing. Can anyone conform this?
