Assuming it's going to be used on a C-3 Corvette, you'll need the large, rectangular plate, that covers the entire top of the m/c. I've used a Motive bleeder with success, on several cars, but I do things a little differently. because I don't like to deal with spilled brake fluid, I use the Motive tool for air pressure only.
I use a "turkey baster" to remove most of the old fluid, leaving only enough to cover the intake port. Then I re-fill the m/c with fresh fluid, install the cover, and pump up the Motive "tank". I then bleed the brake lines, but carefully watch the fluid level in the m/c. There should be enough fluid in the m/c to bleed one wheel. Then remove the cover, refill the m/c, reattach the Motive tool, and do another wheel.
yes, this takes a little longer, but it's not as messy. I had an older "bleeder ball" that pushed the fluid from the tank, under pressure, but every time you disconnected it from the m/c cover, you got a 4-5 oz. "bath" of brake fluid....not good.

As mentioned above you need the rectangular "early domestic" adapter.
Throw the supplied chains away and use 2x c-clamps to hold the adapter to the MC. I also smear a little chassis grease around the perimeter to help it seal. This way I have no leaks and I put the new fluid in the motive bottle.
I've used mine for years on several cars and don't think I could live without it.
Oh, I did have one problem: The clear hose they supply will eventually deteriorate from the brake fluid and burst. I switched it out with a regular black rubber hose.

Thanks guys. I loved my Motive bleeder but a few house moves and ten years down the line its disappeared! Just wanted to make sure I ordered the correct fitting. And I hated the chain system. I have a few wood working C Clamps that work.

If you have a newer motive bleeder a good modification is to add 1/4" air hose quick connects. This will allow you to keep the bottle pressurized and disconnect the adapter to add more fluid to the master.

With an old turkey baster remove fluid from the master so it's down about 1/2" from top.
Use the c clamps on the master. Pump up the pressure without fluid in the tank to check for leaks. You may need to even loosen the clamps to get a good seal.
When it holds pressure, THEN add your fluid to the tank.
When done bleeding, tilt the tank so the hose in the tank is OUT of the fluid.
Open the driver side front bleeder and watch the fluid in the clear hose til it gets to the master plate.
Close bleeder and release pressure. Remove clamps and plate. No mess, at least for me.
You may be surprised to see the fluid is still 1/2" from the top.

The chain set up is impossible, but a few good c clamps and this is an invaluable tool.
