If you have never seem an OEM, NOS bearing set for 906 Titanium Rods, this is what they look like https://pbase.com/9146gt/image/36359585.

These are the correct thrust bearings for a 906 racing crankshaft https://pbase.com/9146gt/image/134287112 using Titanium connecting rods https://pbase.com/9146gt/image/73589365. These bearing halves are extremely rare and have been unavailable for years. I was fortunate enough to have found them and made the purchase several years ago. My plans for my 906 engine build is to restore one of my three other sets https://pbase.com/9146gt/my9146gt_906_engine_rod_bearings_oem_set_2_used of 'used' 906 con-rod bearings and preserve the NOS set, maybe donate them to a museum (LOL). They are only new once!

Link to a similar set of Ti Con-Rod Racing Bearings, these are for a later 962 and used http://www.ebay.com/itm/Porsche-935-962-Titanium-Connecting-Rod-Bearings-/230944199479?hash=item35c558d337:g:tq4AAOxyylVRi~Wd&vxp=mtr until the bearing halves are measured, one will not know if they are a condidate for restoration and 're-coating', a risk we all take when purchasing old used race parts.
