You'll find that the PSA part number is totally useless, as from memory they now specify the same part number as DW10BTED4 conrods all the way back to the XUD9TE and tell you to use different bearings (AFAIK DW10TDs were the change over point for the later sputter bearings with tabs reversed). As far as PSA is concerned, they're not a different part, rather an updated design of the same part since the conrods all fit, you just have to use a different big end bearing type past a certain RPO. They updated the design as they were finding that failures were happening, probably down to changes in material quality and the original FEA calculations weren't holding up, so they beefed them up where they deemed appropriate. There was no need to change the part number since it's technically all the same part - why would they want older, weaker conrods to be purchased.
I've noticed even between early '99 DW10TDs from 306s and later '05 DW10TDs out of 206s, even with identical part numbers, the conrods are much bigger in the later '05 engines.
