Comparison of CX7 (top & left) lower trans mount to the standard XR4 (bottom & right).
The gap between the centres is very close - about 84mm each.
The small spindle inner diameter looks quite close - xr4 = 11mm, cx7 = 12mm
The large spindle inner diameter looks significantly larger - xr4 = 12mm, cx7 = 15mm. Both will need a larger through-bolt.
The width of the main aluminium shell is identical at 35mm each.
But the width of the CX7 larger spindle is greater - xr4 = 60mm, cx7 = 66mm - which means I'll have to press up a wider mount to weld onto the cross-beam.
