Sierra rear subframe
Hi guys
I have a sierra rear subframe with 7.5 diff. I intend to use it as it came off of car. However I did not take it off and not sure what is the best
way to fix the subframe mounts, how do they fit to a locost? Im not buiklding a sevenesque car but a 1936 riley with 2.1 pinto and mt75 box so
thought as you guys use the sierra a lot you may be able to assist me. Any pics of the subframe mounted would be good. Does it just need to bolt to a
suitbale bracket with a bolt through the metal bush and some sort of big waher on the other side of the rubber? not worried about the diff mount
thats easy.
Cheers

Most 7s don't use the rear sub frame, the diff and wishbones are mounted directly to the chassis as mine is. However a few did most Robin Hood
chassis did as some Tiger chassis (not too sure about Tigers). Most likely there are a few more. Sounds a interesting project. I'm sure
someone will have a pic, welcome to the fold.

Smoking Frog is right Robin Hoods (certainly Series IIIs) did use the sub-frame, so I'd suggest a look over at www.rhocar.org
RH SIIIs bolt the whole thing up tight and the two rubber mounts at the front are bolted up tight, along with extra bolts, so that the bush can no
longer flex.

The Robin Hoods also have a very thick metal plate with an upturned bit for the A arm to bolt onto
Several M10 bolts clamp this to the Monocoque
The big rubber mount can be disposed of and metal plates with crush tube put in its place
On the Hood the rear mount is retained and bolted to the rear monocoque boot floor which is reinforced with angle and a load spreading plate
Some early hoods used the coil springs but most used coil overs, you would need to fab mounts for the top and run the bottom off the rear arm shock

Cheers Guys
Hi, The only reason I was hoping to keep the rear subframe and rubber bushes was, that I have a narrowed Jag IRS Powerlok in my other car a Jackal kit
(30's inspired) car that I installed as per the old hot rod style, solid mounted. However the transmission noise is quite annoying with the
roof up, cant hear much with the roof down, though side exit pipes and 3.9 rover sound helps that.

The Riley is going to be more sedate though hotrod styled, so wanted to keep internal noise down and thought the rubber bushes would work well as they
do in the donor, also this whole assembly I have has been fully reconditioned rebuilt and is in as new condition plus, just needs colour-coding to the
future body colour. I did not want to use hard mounting or as has been done on some I think Pilgrim mount the arms only. Also as a complete subframe
it will be easier to drop out to work on if needed. I am going to use shocktec ali coilovers rather than springs and shocks.
Will have a look at RHOcar as suggested to see if they have any pics of the mounting.
Cheers
