Beam Help

[stu8v 68 1 Cars]

I think i may unwittingly have an early beam......

 

Do you guys know if the difference is just in the splines at the ends of the beam and in the swing arms?

 

The original bars i have measure approx 22 and 24mm dia over the splines

 

My new torsion bars are 24 and 26mm approx over the splines

 

My issue is i have nothing to compare too beam wise as the other i had was scrap so it got binned!!!

 

Note my new bars (from 309pug) fit perfect in my zx swing arms though.

 

any help would be appreciated as i've got steam coming out my ears lol

 

Although i suspect i need a late beam tube which is a pain as this ones just been blasted and new bearings......

 

cheers

 

Stu.

 

Oh and i broke my thumb on this one getting it apart, Grrrrrrrrrrrrrrrrr

crikey, didn't think anyone would find one of these beams, I think cybernck is after one

 

I think some geometry was different as well as the smaller splines.

Guess Ill have to start again. Grrrrrrrrr

LOL. Very early rear beams have 28 teeth on each end of a torsion bar, while new (e.g. standard) ones have 30 and 32.

 

Can you confirm that yours is like this?

Ill count them tomorrow but Im certain it will be as you describe.

Just counted and they are 30 teeth on the big end and 28 teeth on the small end

 

Agree new bars 30/32 teeth

Phew, hopefully just sourced a new old stock beam tube.

 

Amazing what people keep in barns....
