Sliding door rollers but is my van early or late?

[MattBW]

So the middle runner on the camper needs new rollers. The older owner didn't fancy the 60quid some vendors are wanting for the vertical one and just put a 50p in there haha.

I need all 3 of the rollers shown, but I don't know if my T25 is early or late.
As its a 1986 its kind of in the middle.

Looking on brickwerks they do the vertical for late and early 21quid, the horizontals only for late.

Are they all the same? Does it matter? Is my van "early"? Judging by the brake plates I was sent recently that didn't fit, its early not late.

Thanks for looking much appreciated. I can take another photo later if needed. Brickwerks seemed to think its late too, so I am happy to order them up based on two expert opinions.

I think 86 must have been a change over year, some parts seem to be early and others like this late.
