Picked up both parts and installed them today. A few notes on fitment: -The pushrod that connects to the brake pedal was too long for my 1977, I had to chop the end of it (twice, because I didn't want to chop too much) to get it to fit. -The neck or whatever of the booster didn't *quite* want to fit into the hole in my firewall. It was seizing on the top, so I filed out the edge of the hole there a bit and also the brake booster neck a touch, and everything fit alright. As someone noted earlier, the neck/pushrod isn't directly centered in the four bolts that go through the firewall, but it looks to be located in nearly the same spot as the stock one was anyway. -The brake line connections for this Tacoma master cylinder are located on the side and not the bottom, which means I need to run fresh lines. Thankfully, these are short runs to the junction just below, so it's nbd. A few pictures after install (yes I know I need hose clamps on those vacuum lines between the booster and vacuum pump)

This is a just a 14mm x 1.5 LH nut I'm pretty sure. McMaster Carr? Or belmetric.com https://www.belmetric.com/left-hand-nuts-zinc-class-8-c-1039_1042_1055.html
