Need a PCI-Express low-profile modem

Dial-up - I know, I know. This all the internet access this person can get right now. System is an Acer Aspire. Had a low-profile PCI-Express modem in it. Got fried. Now I need a replacement.

I cannot find one of these anywhere. Modem has on it:

Concorde
M874179U
D-1156E#/A10A GP
LSI

I found a Zoom modem that will fit, except for the bracket - its full height - there is no mention of a low-profile one included. I can take this bracket off and perhaps one of the screw-connectors will line up....

Any information would be appreciated.
