Looking to buy a head gasket and some head bolts from my local motor factors but he only lists them for a XR3i and can't find any specifically for an RST. I know there quite similar but don't want to buy the wrong 1 if ya know what I mean!
Here's another twist!

He charges around £25 for a Payen H/G for the 3i but lists a Payen H/G for an XR2 for £10! if the RST is the same gasket as the 3i, is the XR2 not the same aswell?
