new top wishbones question
Picked up my new bones from MK. Some of you may remember that I "parked it" in a hedge a while back. Anyway, In the process of fitting,
and the top bones are max 2mm wider apart at the chassis mounts. Can I "persuade" them in or take some off the poly bushes? Options please

Either one of your proposed solutions is likely to lead to excessive stiction which is bad news - could severely compromise the way that your
suspension operates. Either send them back or get them remade or modified by someone who knows what they're doing.
Sorry but my view on these things is you own a performance vehicle and as such major components should work as intended as a bare minimum!

Nowt wrong with that answer - just didn't want to ring Danny without looking at other options. My chassis is one of the older ones and the
original bones were round tube whereas MK only use oval now. Its about a 16th inch.
Just looked again and even the old bones don't sit in the mounts equally spaced...

The problem isn't unique to MK but you're certainly not the first to experience these issues with their cars. It's not quite so
helpful now you've bought them but I'd be tempted to ask someone like Flak Monkey to make them in future - perhaps off a simple wooden
jig.

Funnily enough when I first crashed it I asked on here if anyone could make me a set or had a set of the adjustable ones to flog, and no one was able
to and I missed a set for sale. Being way down south doesn't help.
Tother side was as tight coming out, so I have fitted them for now and will get the person setting it back up to have a look/think when it goes to
them. I expected the bones to sit in the middle of each bracket... was a long drive up to MK too on monday

Again not so much help now you've got the new bones, but having built and rebuilt (for the same reason) an an Indy of the same vintage I'd
strongly recommend buying (or having made) a set of top bones using rod ends. Not only will this overcome any minor tolerance issues, but will allow
you to achieve the right amount of castor and improve the self centering and handling noticeably (might prevent further hedge trimming work  ).

Will the bones I've bought be able to be fettled - ends cut off and rod ends fitted?

Should be possible with the right measurements and equipment. IIRC Hellfire on here did just that with his Indy wishbones a few years back - might be
worth a U2U for info.

They were GTS bones I think.

We did have GTS wishbones fitted at one stage but we weren't impressed with them, so reverted back to MK wishbones although with a few slight
modifications to incorporate a camber adjuster and rod ends for castor.

Thanks everyone. I'll look to getting something made up when cash flow has improved!

I modified oval MK bones to incorporate rod ends as per Hellfire. It was fairly easy and te car now self centres well - not as strongly as my tintop
but it's pretty good.

Mind me hogging your thread Hobzy?
Just wanted to ask what was used as the adaptors on the converted wishbones? Is it just chunks of steel shaped and threaded?
