Radiator with Flow Pipes on one side

We live in an old house - radiators have flow pipes on one side only with what I believe is called a "worm" in "plumb speak" which sits inside the radiator. This was ok on the old radiator that was there as the "worm" was able to just lie in the old radiator - the new radiator is of course different and the "worm" will have to be cut to fit into a tiny hole! We are trying to replace old radiator with a new one without having to do any pipework and ripping up floorboards etc. Anyone got any advice on what approach we should take with the "worm" situation in the radiator?

adjust the pipework so that one pipe goes in each end with new valves, best to lift the floor as it is neater, but you could run 1 pipe along the skirting to the other end,

Yo cant it will have to have valves either side , new rads dont take an insertion tube
