Question on torpedo cars (re part 48310) [Solved]

[knotian]

I'd like to build one of these and one detail escapes me.

What combination of bricks allows the conical ends (48310) to connect?

Is there a cone with reversed studs? I can't find it.

Thanx

Use a technic axle and brick with + axle hole.

Found a way to use a couple of 1/4 round bricks and technic pins. Makes a gender changer and works good.
