Securing bones
What type of bolts have all you guys used to secure the wishbones at the chassis end?
I have been unable to find anyone who will make some custom shoulder bolts for me (only looked and contacted people on the bay as of yet).
I was thinking about getting some thin walled tube, cutting to right length and putting a standard bolt through with washers on either end.
How long can i resist the temptation to drop a V8 in?

hmm, was looking at your photos when you were asking about the steering arm hitting the wishbone. whats wrong with normal 1/2" or M12 bolts?
what size are the holes in the wishbones? just normal bolts should do the trick i would think.

The top ones are 15mm dia and the bottoms are 20mm. Would normal bolts be ok? I read somewhere that the shoulder bolts are designed for movement of
the wishbone.

like thingy up there said (sorry, can't remember his name  ) bolts are only threaded some of the way down, set screws are threaded the whole
way. get bolts, and you're sorted
they are usually just threaded at the last 1"

bolt
set screw
sooooo, if you use 2 bolts per wish bone, in the normal way, that should be fine for you i'd say. 8.8 grade is fine, but these days i'm
liking cap head bolts, which are almost all 12.8

I struggled to find any bolts, in the end popped down to the local agricultural suppliers, they have loads of odd ones for tractors etc.
Harper and Edes are on the road from Lewes to Uckfield/heathfield, I bet you go by them all the time, have a trawl through thier boxes.

Sorry, is it just me or is it scary on here sometimes  - you're building a car from scratch with a seriously heavy, seriously torquey engine
and you don't know the difference between a set screw and a bolt............or were you joking about not knowing that......... hmmmmm

Try your local aircraft repair facility, you want AN spec bolts. To measure length of shoulder required in inches then devide into 1/16"
5/16" dash 5, same for diameter 1/2' bolt dash 8, They also come with 1/2 depth nylocks for areas of little space. Overall length of bolt
requires 3 threads showing after nut is tight. If you can't find them in the UK, Aircraft Spruce and Specialty in US, good prices and a great
catalogue. P.S. Gets even for us Canucks buying half our stuff from the UK.

Why make everything so difficult for yourselves, just order the size you want from screwfix and get it next day

If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

20mm! I think you may be better off getting a spacer turned up to fir the 20mm part, with a hole through the middle for a more sensible sized bolt,
e.g. M10.

Are you using donor wishbones? If you're using anything designed for a 7 then the holes in the wishbone are designed to have a polybush put
through them not a bolt.
If using a shoulder bolt you'd need to be using a bearing, you can't just run a plain wishbone tube on one.

I don't think that's his intention. The original bolts look like this:

Hope not, but quote:

made me worried.
Maybe a picture of the wishbones in question would help?
