Subframe locating pins?

[Mudgey]

Been posting loads today, but here is another question!

So whilst I was fitting back my nicely welded and painted subframe I noticed that it can move around a good few mm, I could not see any locating pins or whatever to make sure the subframe goes back in the same place, so whats going on? Surely it cannot be good for the suspension alignment if the subframe is fully one way or the other? The only answer I can think of is to make some locating stepped washers to fit between the chassis and the subframe. I also think these should be used on the lower control arm as the hole the bolt goes through must be a good 2mm larger in diameter than the actual bolt!! Is there anything like this available already?

Apparently these are called subframe collars, does anybody do them for a prelude?
