Done many of them. If you use the right parts you will have no problems at all. A couple of "be carefuls"-adapting the rear hard line to the proportioning valve (different size), and be sure to get the angle brackets for the rubber/hard line joint on the front-many of these are thicker on disc brake cars & you will have sloppy connections if you try to use the originals.
If you have a choice, the '71-72 master cylinder is generally cheaper, and there is only one proportioning valve (frame mounted). The '68-70 uses a proportioning valve mounted on the master, and a junction block on the frame. The later setup is a little cleaner, though both work fine.
