Where can I get a Hydraulic clutch for 383 dart

Got the kit.It fits real nice on th transmission nice bracket included.As for the Master cylinder it came with no type of mounting brackets .I have worked on ths foe 3 days and don't really see were there is a good place to mount it.I called Chucks and he said it sould be mounted where the Master cylinder rod will meet the pivot point on the clutch pedal.That looks like it would be next to the brake master cylinder area.Ya right, no flat surface in that area to mount the master cylinder to.I am stuck right now I don't want to hack my firewall and am not crazy about drilling a 1 1/2 inch hole for the master cylinder.There is now way to mount it under the dash like Chuck said was possible. Any ideas guys.... Thanks,Jim
