They do now !

So I’ve just measured it and it’s at 49 and 1/8”, so only 1/8” narrower!

so subframe looks to be OK.  that leaves the trunnions themselves or the bushes you're using

 

trunnions - you want c.92mm to the shoulder below the threaded section. the shoulder butts up to the inner mounting presumably to stop the bushes being overcompressed

 

 

if the trunnions are ok, then it only leaves the bushes as these fix the relative position of the mounting brackets to the subframe

 

edit : just noticed you appear to have the bushes fitted the wrong way round.  may be part of the issue

I originally had them fitted the way in your picture, but this still didn’t help. Made it fractionally better but not quite there!
I’ve fitted them this way as nicklouse had this picture of what looks like the workshop manual (posted on page 1 of this thread) that shows the bushes orientation. I’ve attached the picture here.
Measured the trunnions at 92 and 91.5 so they’re okay!

Correct Rover 1996 year manual.

..in that case, although it's not a '96 car, but i am using the single piece bushes, i'd better put mine on the right way round

Any updates on this as I’ve just come across the same issue. But on a heritage whole floor and the old bushes still in the subframe?

I’m afraid not! I’ve set my trunnions at the 50.5” gap and then lined the new panel up like this. I will look in further detail when I come to refit the subframe!

I think you’re making this rather more complicated that it needs to be.

If your heel board measures 50.5 inches from centre to centre on the trunnion mounting holes the panel’s fine fit it to the car.

If you’re struggling to fit the subframe then loosen the trunnion pins so that you can wriggle the trunnions around and get them lined up.
If you’re really struggling then bolt the trunnions with the rubber bushes fitted then lift the subframe up and slide the pins in.

Its an old car repaired over the years by questionable parts made on old tooling using bushes of unknown properties.I would bolt it in and forget about it.It is massively over secured and is going nowhere once in.Just my view.Steve..

[Mcbudge]

My biggest concern was that the trunnions were not actually sitting against the shoulder of the bush, and I was just wondering whether that was okay or whether there was an issue with my subframe. Like I’ve said, I’ve spaced my trunnions to 50.5” and have lined up half the rear heelboard on this, then will line the other half up the same next week.
