The only slave cylinder that I have to work with a Toploader and a Lakewood bellhousing is a Wilwood slave cylinder. Unfortunately, you would have to fabricate your own bracket. Otherwise, the parts are readily available and ready to ship.
As an example, you would need:
(1) MCL-16915 - T-Bracket - $38
(1) MCL-16935 - Clutch Fork- $62
(1) MCL-16042 - Throw Out Bearing - $65
(1) Wilwood Slave Cylinder - $80
If you wanted to try to get parts for your current hydraulic bearing, I'm pretty sure it's part number MCL-1305. If so, there are replacement parts available:

If you knew exactly what you needed and wanted to go this route, you could email me with the part numbers, I could get you pricing, and then send the parts to you.
