Part numbers needed.

["Peter Jones" <dato1500@hotmail.com>]

Hello listers,

I need some help with part numbers for pistons and rings for my U20.

Currently my roadster has a two .020 pistons and rings and two .030 pistons 
and rings.
You have to love half baked mechs who use what they find. I need to get my 
block re-bored and rebuilt as I have over 60% blow down into the block 
during idle.

any help on these numbers for the .030 or .040 would be great.

O.T. paid $1.42 per litre for 98 octane fuel this morning.
