The bad news is that the complete Aisin unit from the Cressida with ABS (1-1/16" bore) is discontinued.. You can only get them remanufactured with ghetto reservoirs because Toyota/Aisin discontinued the factory reservoir. This is/was the sought after piece that Dr Jones used to sell, and it was a well kept secret until until more folks starting searching for options after upgrading to various BBKs.
However, another 1-1/16" MC is available from the 4-Runner[-2nd gen w/ 3.0L V6], and it appears very similar to the Cressida unit, if not identical aside from the reservoir being different.
Also, I really want to say the A70 uses a 2-port MC on both ABS and non-ABS cars from memory. This is at least true of the ABS cars such as my own.
