"Ok, so can you run with just hi-lo's on the rears??? How much fiddling will it take to get everything right back there? I don't want to mess with suspension angles etc..."

Not sure what "just" Hilos infers but yes, they're a straight replacement for the standard trumpet. 

There's no fiddling to get it all back in - the only hassle is getting the old stuff out - if its welded itself together after generations of use.

Replacing trumpets/cones etc does not affect rear suspension settings (other than height)..

On the weekend I removed the fuel tank from my Traveller and was intersted to see that the rear subframe has the holes and reinforcing on the rear crossmeember for the hydro's schraeder (sp?)valves.  Does that mean I have a wet subframe fitted or did all subbies come with the hydro fittings???  Is there only one kind of rear subframe??  This is for interest only as it works perfectly well as is....

While reading Lindsay Porters book on restorations I found a paragraph where he mentions that the LWB cars only had the longer trumpets to give extra ride height.

The grey wagon will get a new lease on life this winter. 40 year old paint is really showing its age, some panels need replacing or repair, seam sealer on the roof is gone and most likely a new interior to match the new exterior.

The car has served us very well the last 8 years or so. Still running with the 1098 she was purchased with, although I did swap transmissions last year

What are we in for?

Terry, that is why I hang around here! Learn learn learn!!! How much did you have to do to your car? it looks perfect from what I can see.

The rear is pretty straight forward. The adjustable brackets allow you to equlaize the settings side to side.

The cones do drop, but with stock trumpets they would be very high to start and then drop to a reasonable level.

Our cones were only 4 weeks old and I adjusted to a more reasonable level before we left. They defintely dropped further to the point where they were rubbing.

I think the gray wagon caught something from that red saskatchewan wagon, not the other way around...

Ok, so can you run with just hi-lo's on the rears??? How much fiddling will it take to get everything right back there? I don't want to mess with suspension angles etc. Brand new rubber donuts will flatten that much??? Not doubting you Terry, just trying to figure all this out.

Our cars decided this needed to be done.  That is the last time I park next to you...

Having the ability to make height adjustments due to load or cone wear is priceless:

Interstate 80 took its toll on the 4 week old cones that needed additional roadside adjustment on the way home from MMW...

So the longer trumpets would raise the rear about 1 1/4" over the other type.  Sounds like personal choice to me. Use whichever trumpet is to hand and modify (with file or shims) to taste.  Or just change to HiLos...

Measuring from the shoulder all four of mine are 12 3/8 = 12.375

So did subframes change to go with the change in geometry, or this was a manufacturing decision and not an engineering decision?

Are all rear subframes the same?

That is what I measured on mine cool!!! One less thing to buy!

Found this quote ...

 

And for the record the front trumpet height as standard is 3.750" and the rear is 12.375" on the latest post 1979 cars and all vans/estates. The earlier ones were around 12.125". This is from the knuckle end to the spring platform face, both measured from where the spring butts up against it, NOT the over-all height.

old version 21a1032 = 13" overall length

relatively new 21a1684 = 12.75" overall length

I am pretty sure that is correct.

I will do an accurate measurement later today.

So... for the slow people out there(me) what I have is correct for my 65 traveller.

the length difference explains a long-standing observation regarding the Saloons: early model Saloons had their tails tucked down, late model Saloons had their tails lifted.

My guess would be the rear subframe remained the same. The longer trumpets would create the observed "lifted tail" look.

No the new are the more recent from the modern saloon. The newer versions also have a steel insert where the knuckle inserts. They are the same size though. The wide angle on the iPhone make them look a little different height perhaps.

This chart from another site lists the current versions. 21a1032 is not listed.

2A7375	STRUT, steel (also known as 'trumpet')	2	Saloon models, 1959-61.
21A1683	STRUT, aluminium (also known as 'trumpet')	2	Saloon models, 1961-84; may be used on earlier models.
21A138	STRUT, steel (also known as 'trumpet')	2	Traveller, Van and Pick Up, 1960-61.
21A1684	STRUT, aluminium (also known as 'trumpet')	2	Traveller, Clubman Estate, Van and Pick Up, 1961 on; Saloon and Cabriolet, 1984 on (may be used in pairs on earlier models).

 

So I have a question on subframes to match. If I need a replacement for the 64 Traveller, can I use a more recent version? How many rear subframes were there? The geometry had to change in 84 if the same strut for early LWB and post 84 sedans is the same.

The van. estate and pick-up up rear suspension used slightly longer trumpets in the rear.
I would suggest ( If renewing suspension ) upgrading to a quality set of adjustable cones

Looks like I need those trumpets after all! I assume the old are the sedan's, and thus are shorter?

Side by side:

Old 21A 1032

New 21A 1684

Anyone have the numbers off the wagon trumpets? I can see the last couple... Maybe 2???032. ?????? Thanks!
