On the opposite side of the firewall from the fuse block, there is a 'bulkhead' connector, where the wiring harnesses from under the hood connect. You'll probably have to remove the windshield washer reservoir, and maybe even the clutch master cylinder (if it has one), to get to it. There is a single hex-head bolt in the center of this bulkhead connector. When the bolt is removed, you can unplug the harness assembly from it by pulling straight out on the harness. After that is removed, you should be able to see the heads of two more hex-head bolts, in opposing corners of the bulkhead connector. Remove these two bolts, and the fuse block and bulkhead connector can be pulled out from under the dash (within the limits that the under-dash wiring will allow).
