100mm is good for stock 2,5td, not STD. It's a lot thinner than w210 110mm or w211 120mm, hole diameter is only one factor. I recommend to take 4 bolted 120mm disks from scrapyard, if it's used also on 700lb/ft 65AMG it will hold that 400lb/ft with ease.
One important thing is that propshaft should be on right angle compared to gearbox and differential, so flexidisk is straight between flanges.
