Information is power they say - maybe it should actually be *access* to information that is real power! :lol: It actually proved to be a bit easier to find what I was looking for than I was expecting.

Here is the old trailing arm as removed from the car. (note the flush sleeves):

Image

and here's the new trailing arm ready to go back on - at this stage I hadn't noticed the discrepancy, but with hindsight looking at the photo, you can clearly see the inner sleeves sticking out - cue an Ooooops! moment as I tried to refit it to the car and failed: :oops: :evil:

Image

And finally, just in case anyone was looking at the old arm and thinking a lick of paint would have sorted it, here's the other side: :shock: (funnily enough, the tubes were fine)

Image

All I did was shorten the sleeves to fit the space, I didn't actually produce any measurements, so If you have the means to confirm the measurements of the two types then I think that would still be useful, Jim? :)

I'm sure I measured them previously - but can't find the post (if I made one) - will do it again this week :-)

Thanks for the input guys - I half expected one group to say inner and one group to say outer.And I suspect that may be the case.And Roger's shortening down of them (all ?) as necessary is equally surprising with his later galv chassis.

Jim-might be useful info but I don't particularly need the dimensions for my re-installation -thanks for the offer though.

It's interesting that the previous set of metallastic type bushes from GW were all long ones and the new poly ones, originally bought from QRG(but not bought from them by me) as a car set, are all the short ones.It is all a bit fishy.

My own opinion is that I could probably get away with merely tightening the bolts up until the tube was trapped anywaybut I will probably shim them as required if it feels a bit too forced-if you see what I mean.I can't envisage a design reason to have one bush tube just slightly longer than the other-considering that the (poly) bushes themselves are all the same length.

Looking to buy some trailing arm poly bushes. Best source / cheapest?
Superflex direct, QRG, GW, any idea?

Got a set from QRG last month - not the cheapest but the right ones arrived next day?

Just realised that I never posted the pics and measurements of early/late mounting brackets :oops:

I am just packing a pair of NOS ( likely to be SE6a) rubber ones for Curborough. Naturally they will be different to the SS1.

So I don't know why I bothered to say it, apart from "fingers engaged before brain" again.

Right,
I'm looking to pin down the trailing arm bush fitment thing, as it's all a bit vague, and the chance of making mistakes when ordering is far too great!

My observations, on fitment and inner sleeve length of the bushes -

The GW supplied new metalastic bushes I have measured up at 71.5
Superflex currently sell a 68.0 and 71.0 length inner sleeve with their kits. "late" cars being listed as taking 4 x 71.0

HOWEVER. I have not a single trailing arm, nor used bush that exceeds 70.
Of the 22 bushes I have measured-
A range of 66.0 to 69.5
Mean of 67.8
Mode of 68.0 ( 6 off) closely followed by 69 (5 off)

Full listing of occurrence -
66.0 - 2
66.5 - 2
67.0 - 4
67.5 - 1
68.0 - 6
68.5 - 1
69.0 - 5
69.5 - 2

An example of the variance -

The trailing arms (or bushes) have been removed from a range of cars, non glav SS1, galv ss1 (992, 995, 1148) , an SST and a MK2 Sabre (2118) so where does that leave us in terms of pinning down the actual fitment in relation to age / chassis number?
The only statement I can make is that all of the narrower bushes were found in the inboard position, and the trend would suggests this applies to galv chassis, with the exceptions of the SST and Sabre arms I measured.
The range on the outboard bushes being 68.0 - 69.5 across the board

Some have claimed (Alan Wells, Stew Brabham) that their cars required the wider 71mm tubes from Superflex when fitting poly's, but it doesn't seem to conform with what I have above, which strongly suggests there is NO fitment for the 71.5mm metalastic bushes presently supplied. I have noted that measuring the chassis brackets, they do appear to taper from approx 71mm at the cross tube, narrowing towards the mounting holes. It is therefore feasible to squeeze the 71mm tubes without causing major distortion to the chassis.

I would suggest that during SST / Sabre / Sabre MK2 production, Reliant revised the bushes / spacings to use the wider tube. Subsequently this may be the cause for the GW stock all being 71.5, if they are a throwback from the end of Reliant production, I shall pose the question next time I'm in touch.

Any further scores for the doors if you have them would be great.

Thoughts gentlemen?

I have previously measured and photographed a selection of chassis brackets - will try and remember to post it on this thread :oops:
