A set of wishbones arrived today... I've never studies a lower-wishbone before, but is this design the 'norm'???

I thought the book stated to slot the plate at the end into the tube then weld it, rather than weld to the top of the tube?

book bones would have used Tina ball joints that have four bolts. Two of them would have bolted through where it angles up. Every one usses the maxi ones now.

I still use Cortina ones as they spread the load into the wishbone plate a bit better.

I would make a small modification to the bones as per this image - several threads about this over the years

The book shows them welded on top.

Another differance to yours is the top plate was curved at the back. To stop stress raissers.

Those bones look fine for a book car or trike with book front geo' I dont think I would hang anything to heavy on them though, no monster v8's

Cheers guys. Won't be a lot if weight on them... reverse trike about the 300kg mark.
