Are Clio Mk1 and R5 subframes the same?

As per the title, are Clio Mk1 and R5 subframes the same? I'm looking to use one to make a jig to make a tubular maxi subframe and push the lower arms out by 50mm each side. I've already swapped in 182 cup lower arms etc so need to get a spare subframe with all the same mounting points as a Mk1 Valver subframe.

They are similar but have differences from memory. I recall the clio has a bush on one subframe mounting point and the rad mounts are different.

Hmm not sure about the bush but the rad mounts aren't required anyway

If the mounting points match then you would be better off without the bush. Valver/williams have the bush on o/s rear subframe mounting point for some reason.
