Hi zurferjoe,
When i did mine our re-conditioner wouldn't attempt them without the lip, calling them "flanged" liners. He wouldn't be responsible for them slipping or turning. I couldn't get any such liners locally, but Adrian Wright at IMD pistons supplied them (together with top quality pistons and ring sets, that bedded in great and have stayed brilliant). Those liners just had to be trimmed off at the bottom..
