done some comparisons
the red cross-member is the one i bought (33
) and the black one my suds'
they are pictured upside down so that the point where they mount to the chassis is touching the bench top, that way the only shared point of contact when fitting either one is in the same place for taking the measurements.
results are -
in the first picture the distance between the bench and the top (would be the bottom when on the cars) shown as A to B is
165mm on red one (33)
150mm on black one (sud)
also note that on the red one there is a gap along the centre, on the black it touches all along
in the second picture the distance from C to D which is from the bench surface to the bottom point of the mounting space (when it would be on the car) is
115mm on the red one
80mm on the black one
the distance between the mounting holes E to F is
85mm on red one
70mm on black one
also the angle of the mounting point on the red one is very pronounced, on the black one it is parallel to the bench, therby creating a twist on the forward arm?
hope this is of some use/interest to anyone
