Feltonik (real name?), Welcome to the list. I hope your experiences here will be as great as mine. I have personal experience with this on my 70 Javelin. I converted it to front disc brakes from drums all around. In 1970 model AMX and Javelins the factory installed a proportioning valve on the inside of the passenger frame rail in front of the rear axle for disc brake equipped cars. The proportioning valve is not installed on the all drum setups. Since my car did not have the regulator I simply purchased one from Summit http://store.summitracing.com/partdetail.asp?autofilter=1&part=SUM2DG3905&N=700+4294922533+4294918719+115&autoview=sku As I was replacing all the nasty looking brake lines I installed the valve in the factory location by fabricating a simple bracket. I then bleed the system, bedded in the new pads, etcetera, and adjusted the valve until things were satisfactory. May I also mention that my disc brakes came from a 75 Hornet. I purchased a new master cylinder from NAPA for the Hornet and installed it in my Javelin. The drum master cylinder from your 70 AMX may not be adequate to operate the disc brakes.

I am converting a 70 AMX from drum all the way around to front disc.? I have everything I need except the proportioning valve.? I have?been told everything from I don't need one, to buy an adjustable one (but get a brake professional to adjust it), to use the GM valve that was used on vehicles such as the 70 Impala.?
