'70 B-body 4-wheel manual drum brake lines

[hemi68charger]

Hey gang..
Just curious, does the '70 B-bodies with manual all-drum brakes have the two metering valves like on the disc brake cars or just the one valve below the master cylinder? Anyone have pictures of a finished product for '70?

Thanks..
Troy

PS: Below is from my former '68 Hemi Charger R/T with 4-wheel drum brakes.... Would it be like this?

Troy my 70 had/has 4 wheel power drum and has the same as your photo.
