90 Polybushes

Hi all, I've just picked up some black polybushes for my 90. It's a 1990 and I've just opened the box to realise I've bought 1999-2007 bushes, are there any differences? If so what and will I be able to use these bushes on my chassis?
Cheers, Dan.

Is there any chance you can swap them back for the correct year or did you buy online? Wouldve thought itd be the same but if theres different years there must be some differences

If they are black then they aren't genuine Polybush, they are polyurathene but not the genuine article.

Early vehicles had narrow front radius arms so no, they won't fit (I think the change over point was 1993).

Personally I dislike polyurethane bushes.
I had happily run OE bushes for many years but in 2010 fitted some Bearmach polyurethane items and immediately found them too harsh. I decided to stick with them but finally removed them last weekend and went back to OE. The BM items showed no signs of wear and were as good as the day I fitted them but they were just not for me.
