Found the problem. Roll pin holding the fork. Thanks to all.

Sorry for misunderstanding. Thought he was referring to a clutch fork. Referring to the diagram I see what may be the problem. Thanks.

But would a defective shift fork affect just the 3rd and 4th gears?

Had my car at the track and mid session lost 3rd and 4th gears. Thought the whole tranny was toast and pulled over onto the grass. Found 1st, second and fifth gear are working. Car is a '71 with a 5 speed replaced by a prior owner. There was no grinding or noise prior to losing the gears. I feel nothing different when I shift into 3rd or 4th gear. Just no power. Sound serious or simple?

Pete, Thanks for the information. It is exactly what I was hoping for. Makes my project a lot easier. Tom

Six Shooter, Miles You are correct in that the '71 has the rear reservoir (smaller) servicing the rear brakes and the front (larger) servicing the front brakes. That is the way my brake lines are situated. The newer Datsun MC reservoirs are reversed. As shown in your photo of the Wilwood MC the "F" is under the rear reservoir and the "R" is under the front reservoir. Since my lines are not long enough to reverse position can I hook my rear brake lines to the Wilwood rear reservoir even though the is a "F" designation below the rear and the front lines to the front of the MC which has a "R"? My check valve is located only in the rear of the MC because I still run rear drums. Fastzcars Thanks for the advice. I have made the correct Metric to American Standard fittings with a female 10x1.0mm convex seat to a 3AN male. I had to shave off the convex seat to fit but it works.

Miles, Appreciate you pointing me to the other forum questions/answers but with reading it several times it still does not answer my question. With my old MC the hard brake lines were positioned so that the rear line were placed under the rear reservoir and front brake line under the front. The Datsun MC is labeled with a "F' under the front reservoir and a "R" under the rear. The Wilwood F and R is just the opposite. My hard lines will not stretch far enough to retain the same positioning as the old MC. Can I run the rear lines to the rear of the new MC even though there is a "F" stamped under the rear reservoir? Thanks, Tom

I have drums in the rear. So I assume that as long as the check valve is in the front section/reservoir then I can still position the rear brake lines to the front section and the front lines for the rear section (without the check valve)? The check valve is what reduces the brake fluid volume for use in the rear drums? Also, I understand the removal of the check valve but what is meant by removal of the "reservoir"?

Replacing my '71 brake MC with a Wilwood 1" MC due to an upgrade of the front brakes to the Toyota calipers. The old Datsun MC has the front reservoir used for the rear brakes and the rear one for the front brakes. There is also a "R" and "F" stamped under each reservoir. The Wilwood MC has the "F" and "R" in reverse order so I assume the front reservoir is meant for the front and vise versa. Due to the old brake lines entering the MC underneath being to short the stretch to the opposite inlets of the new MC can I still hook up the brake lines the way the old MC was connected? Is there a difference between both? Thanks for the help.

Here is a picture. The booster on the right is the 240 booster with the fork. The 280z booster is on the left. Much bigger threaded rod.

Doing the upgraded Toyota front brakes, with a Wilwood MC, to my '71 and ordered the 280z booster from Motorsports and was sent the booster without the clevis fork. This fork attaches to the brake pedal arm. I thought my 240z fork could be used but the 280 threaded shaft is too large in diameter. Any one parting out a 280z that has one?
