Yes, it's not listed as compatible because you will have to fab lines - which you already know.

Ok so I can get that MC and then buy the lines to convert a single to a dual MC.

Or I guess I could just buy the lines and bend them myself but that seems like a pain in the butt.

Push rod on that 68 MC... is that going to work or what will I need to do to make it work??

For $19.95, I'd use that kit from CJ's rather than try to bend the lines myself. Generic lines come in 12" increments so you'll be doing more bending or cutting and flaring, not fun, to make the extra long line fit correctly.

Buy the kit.

You'll need to change the pushrod for the one on your MC now. Instructions at the bottom of this page-

I don't see a distribution block in that kit... somebody had one that was adjustable for reasonable $$$ IIRC... just can't remember where I saw it... :p

Do I need a distribution block? I thought I read it's not really needed?

apollard · « **Reply #30 on:** December, 22, 2010, 06:16:23 AM »

You don't have to have a new distribution block. You have a brass distribution block that splits the fluid to the front wheels and a single line to the back axle. THe kit uses a plug to block off the distribution block port to the back axle. You then use the brass coupler in the kit to attach the rear brake line to the line supplied in the kit. Then attach the front line from the MC to the existing distribution block, and you are done.

The disadvantage here is that you will not have the brake warning light switch that is on the '67-up distribution blocks. How big a deal this is is up to you - frankly, those old style switches are unreliable[1] - they were the first generation designs for failure detection. I've seen brakes fail on one axle (or be bleed, which simulates the same thing) and the switch never lites the light. Even on some 2-3 year old switches. I personally wouldn't worry about it, but YMMV. If it is an issue for you, you can get blocks from various sources - but, you'll likely have to make your lines unless you buy a kit with a new distribution block.

66 has no brake warning light on the dash.......................

Thanks guys. I went ahead and ordered the conversion kit from CJs. Figures... the master cylinder is on backorder.

I don't feel like waiting, so I called CJs and canceled the MC off the order (it was going to take a few weeks before I got it), just got the lines and going to get the MC locally.

Good call. I buy stuff like MC's from local stores with a lifetime warranty. If the price isn't that different, get the new one instead of the rebuilt one. If you're going to have the car a long time, you'll likely be changing it out again.
