Front seat slides

[Sam Bee]

I am renovating mine and stripping down to have parts zinc plated or powder coated. The seat slides are in two parts (one fixes to the floor, the other to the seat support) which need re-plating after some patches 0f surface rust are removed but I cannot see a way to get them apart, so is there a way, or do I resort to a suitable paint?

I would paint what can be seen and lightly grease the rest, They are a very tight fit and if plated might not go back together !
