Just joined the forum. I'm looking for some parts for the rear suspension on a Prova Designs Miura kit.
On the rear suspension, there is an adjustable length link to allow the alignment of the rear wheels to be adjusted. This consists of two rod ends (one bolted to the lower wishbone, the other bolted to the hub carrier/shock absorber) that screw into a 50mm long length of hexagonal bar.
The hex bar is tapped with a RH thread from one end and a LH thread from the other, hence the distance between the end bolts can be varied by rotating the hex bar, hence adjusting the wheel alignment.
I can find the rod ends easy enough, but can anyone suggest a supplier of the hex bar item?
The reason I'm changing it is I've been told the 1/2" x 1/2" rod end can break under serious driving, so should be replaced with a 1/2"x 5/8" rod end.
I presume you are talking about something like this which I have arrowed in the picture. (I realize it's on the steering but it's the only picture I could find on t'internet)
Looks like the hexagonal bit is there just so you can get a spanner onto it to rotate it to adjust the wheel alignment.
Could you not use a round bar threaded at both ends with a nut welded on half way along for the spanner.
Excellent link thank you. If I use one of the jackscrews and a pair of female rod ends it should do the job well. I'll see if I can get a couple of photos up later.
