355 Suspension Bush Question

I've received my new suspension bushes for the front and rear - but had a question about the front bushes vs the rear upper arm bushes: are they the same? They are identical in size, and are in 2 separate bags of 8 bushings each (but there is no part number/marking to know which is which)... The rear lower bushings are in 2 bags of 4, but the longer/shorter are easier to tell apart...

I searched up the part numbers online but cannot find a size for the front/rear upper to compare/match the bushings I have recd... and the vendor has yet to reply to my emails...

If they are interchangeable, then Im not too worried about it... but if they are different for any reason, Id like to know how so I will look for that to tell them apart...

Thanks!
