Radius Arm to frame bushing dimensions

[Lumpskie]

Like the title says... can any of you guys get me the official dimensions on the rear bushings that attach the front radius arms to the frame? (looking for width, height/outer diameter and bolt diameter/inner diameter)

I'm sure this info is widely available but an internet search didn't get me what I was looking for.

Thanks guys,

Bump!

Not the Same as the front

And the rear is technically not a radius arm. But I would be interested in the same info!

I could measure my new Front Control Arm Frame Mount Bushing Press Tool

 

[mudgudgeon]

Same as the front

Negative.

Rear radius arm bush

This one?

O/D "C" - 53mm, width, 43mm
I/D "A" - 18mm, width, "B" - 60mm
Bolts, 18mm

Measured this morning, so I'll let you decide if it's "official".

 

[mudgudgeon]

I'l let you mangle those into that imperial mumbo jumbo you guys use

Front radius arm bush
O/D "C" - 60mm, width 40mm
I/D "A" - 16mm, width "B" - 50mm
Bolts 16mm

Yeah, the axle mount bushings are different than the frame mount for the front LCA.

But the frame mount LCA bushing can use the same press tool for the rear LCA. Rear UCA is different again.

Ah yep, I thought after I posted there was some confusion between RA, front and rear, and rear LCA.

And, just to be sure... 43mm is the width od the rubber bushing and 60mm is the width of the metal center portion, right?

Correct.

To be a little more specific, the rubber bush is vulcanised to a steel sleeve that is pressed into the RA, the steel sleeve is 43mm wide

 

[shocktower]

Negative.

I stand corrected

Why are you wanting them? I have thought trying to fab up some JJs in there to get some more flex.
