"Here's a picture of the new Moss spindle I bought compared to the original spindle. There are fewer splines on the new Moss Spindle (57) compared to the original spindle (72). Original Rainbow wiper arms will not fit on the Moss spindles".

Wiper arm splines "I replaced both my MGA and MGB arms with "top quality" TEX items only to find they gripped the drive splines poorly. I lost three in the rain, and caught two more just before they flew off. I bitterly regret throwing away my original arms before I realized the issues with the shiny new replacements! My MGB has now been fitted with original used arms I was lucky enough to buy. They fit snugly, with no issues.
"The center arm is an original, the top and bottom, replacement Tex items. The diameter of the replacement arms' hubs are clearly larger than the original, and the 'splines' don't even come close to the drive spline's configuration".

"I agree that the TEX ones are rubbish, but so too are the repro wiper boxes. I improved the fit and stopped losing wipers when I found a set of original wheel boxes and fitted arms with a screw-wedge clamp to the spindles".
