66 impala disc brake conversion help

i need some help, i,m planning to upgrade to disc brakes and i went to the KB and there was an article in there on 66 impala upgrade.but alas the page is now gone i searcher the guys web site and e-mailed him but no response. the problem is that i want to keep my 14"wheels. the thread listed a bracket set that bolted to the stock spindles and used some camaro or chevelle stuff but i don't know who sells the bracket kit and exactly what parts to use. does anyone know who makes them and have a complete parts list for it? i checked the relevant threads in the KB but the company wasn't mentioned there any help would be appreciated

thanks rich.

I don't know if this will help or not, but I've been eyeballing these guys:

Master Power Brakes

Their kits let you bolt the disc brake to the original drum brake spindles.

I converted a '69 Nova to discs with factory parts, & the 14" wheels rubbed on the calipers. I used a 1/2" steel spacer on each side of mine & it worked OK. I have also used OEM 14" wheels from later Novas that were factory disc cars & they cleared fine without spacers.

All '75-up Novas & '70-up Camaros had discs from the factory, and have the same bolt pattern as yours. Malibus too, but I don't know what year they went to discs.

Corvette brakes

We used Corvette disc brakes on a low-budget stock car....the Corvette spindles pop right onto the '66 Impala control arms...
If you keep the stock rear drums you'll need a proportioning valve....If you use a dual master cylinder off a later model GM car, you can plumb in the Corvette adjustable valve....or use the valve off whatever GM car you get the master cylinder from...make sure if it isn't adjustable, that the donor car had front discs and rear drums....

Novas & B-cars are definitely different. '65-'70 B-cars have basically the same front suspension as each other, & discs were available '67-'70. '67-'68 used 4-piston calipers, which are somewhat rare, prone to leakage, and have marginal aftermarket parts availability. '69-'70 use the common & reliable single-piston calipers.

I first used some 1/4" aluminum spacers from a famous hot-rod parts company whose name begins with "M". They collapsed, & one front wheel got swallowed by a wheel well. Sparks, noise, etc. I had some individual bolt spacers (ten, in all) made from 1/2"-thick steel plate & they worked much better. If I had it to do all over again, I'd use wheels that were made for discs, because with spacers, your wheel may not be exactly centered on the hub.
