I am trying to build for my Toyota Bj42 a rollbar . My Bj42 has the rear long jump seats . I hope there is somebody that can supply the mesures

Dimensions A, B, C, and D changed in '77 on the FJ40s. That was the first year the hardtop side windows had the kick-out vents. The '76 and earlier roll bars had a larger radius - A and D smaller and B and C larger. The radius tube would interfere with the latch on the vent window, so Toyota made the radius smaller. I'm not familiar with the BJ42 so I'm not sure what your hardtop side windows look like.
I'll take some measurements later this afternoon of my '77 roll bar.
