All the measurements include the piece that goes into the fittings. I used 1" I/D pvc piping The caps on the front I Probably just cut 1.5" pieces to fit them. The 3 cross pieces are obviously the same length of 21.5" The 9" piece you can adjust to fit the down pipe (42" Pipe). I measured fast so...... Good luck. I winged it when I made it from an S2000 design. These sizes worked for me. Post pics after you completed.
Let me know if you need any more specifics.
