SEIW rear wishbone rose joints.

[KevanP]

Looking to buy a replacement set of rear wishbone rose joints.

Can someone point me in the right direction for them?

I want good quality rose joints.

 

Rough size is:

Wishbone rose joint 10mm dia bolt hole. 1/2" dia thread to wind into Wishbone. Rose head 15mm dia at narrow point.

Should be 7/16 x 1/2 some have used 1/2 x 1/2 with a sleeve in the hole.

Think I may have found the correct ones. Am I right? This post seems to cover it.

I fitted these two years ago. All good. I used the 1/2 x 1/2 inch and reused the sleeve from the original joints. Yours have this sleeve, though it looks a little damaged in your pic. I think I choose the larger size as there is a little more ‘meat’ around the joint. I’d expect the 7/16 size would be fine though.

Edit to add its best if you measure/count threads etc to make sure your new joints go back in the same position as the originals…

Yes those are correct, and you don't require the sleeve 👍

Thanks all really helpful & appreciate all the expert advice as usual👍 I have ordered the  7/16 x 1/2 ones from McGill motorsport at a fraction of the cost of the one's on Westfields parts site, plus these are much better quality.
