Must Be Christmas!!!!!!!!!!!!!
Last week I put out a query to the list if anyone heard of a piston with the
following markings on the top of the piston.
RA5228 STD
Got no response and now I have identified that I need 1 piston 87mm. Really
do not want to buy a whole set. Would be nice to find the original and a NOS
would be the cat's meow.
