If the service bulletin you are looking for is mandated by an Airworthiness Directive, you can use the following site:

https://beta.regulations.gov/

In this case, I believe your SB is mandated by FAA AD 2008-22-12 (docket # FAA-2008-0151)

The process would be as follows:
1. Go to rgl.faa.gov and use the airworthiness directive tool to find the associated AD.
2. In the PDF of the AD, find the FAA docket number, for example:



3. Enter the docket number in the search bar at beta.regulations.gov
4. Click on the correct result and select the "view more documents" tab. The SB should be there (although there are some exceptions).

Unfortunately this appears to be one of the exceptions. There are five associated documents, but the SB is missing.

However, I will note that the AD in question states the following:
"ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes,
P.O. Box 3707, Seattle, Washington 98124-2207; telephone 206-544-9990; fax 206-766-5682; e-mail
DDCS@boeing.com; Internet https://www.myboeingfleet.com."

Probably that is outdated information.
