1303 top mounts

[andy1303]

Hi,
I'm just about to buy new top mounts for my 74 1303 but I'm wondering if I should buy the earlier mounts instead of the correct ones for my year. These seem better made and may have less play in them due to it looks as if the bearing is solid mounted. I'm pretty sure the 3 bolt holes are the same position, but I think the cutout the main assembly fits through on the inner wing is a different size. However I'm not sure whether late cutouts are bigger or smaller.
Any comments? Has anyone experience of doing this? Is there a clear difference between bearings?

Cheers

Andy
