O/S Engine mount - Is the main vibration shock common but the bracket different?

I'm looking at replacing all the engine mounts for my VRS, its 11+ years old & I think they are badly worn. (Clunking & knocking from the engine bay - all other suspension parts are new or have been replaced recently)

I'm got hold of the Dog-Bone mount & the Nearside Gear Box mount but the Off-Side mount is proving rather expensive to buy.

For some reason the one for the VRS seems to be £90 to £110, this is for the mount with part number 6Q0199167DK (This part number supersedes 6Q0199167CS or CE or CC) 

However, it seems that the mount is very common (just search Ebay for 6Q0199167) or take a look here:

http://www.partsbase.org/vw/polo-derby-vento-ind-po-eu-2006-19920-mounting-parts-for-engine-and-transmission/#p-vw-6q0199167dk , the only difference I can see between all the different varieties is that the engine mounting bracket is different, but the actually main shock absorber is the same.

So my question is, could I not purchase one of the cheaper versions (I've seen them less than £50) & just replace the bracket from my current existing mount on my car. They should just unbolt at the top & come straight off.

Thanks.
