86 300E 124.030 with manual transmission. Rear driveshaft bushing.

I believe driveshaft bushing is the correct name for the centering sleeve that protrudes from the end of the 3 legged flange in the rear of the driveshaft.
I drilled the old bushing, put in an old head bolt and pryed it out. The replacement bushing is longer than the old one. 43.6mm versus 51mm. I wonder if this will affect lubrication of the centering pin as the extra space will allow the grease to remain in the front of the bushing. If anyone knows, I could get this job done this weekend, otherwise I'll have to wait.

Thanks in advance!
