Quick question,size of body bolts

[That Daddy]

Hello,was wondering what size of bolts(length diameter,etc)are used for the body to chassis e.g outriggers to tub front,centre,back i dont have the car to hand,thanks in advance

[Chassis 33]

IIRC they are 7/16" UNF the same as seat belt mounts, I'll check my chassis this evening and confirm.

Thank you Ian would appreciate that.

Pretty sure they are M10 x 35 or 30.
Certainly 17mm socket/spanner.

They're a mix of imperial and metric I ended up grinding the captive nuts off and replacing them with metric Nylocs and sticking with the 7/16" stuff for the seatbelts.

Ahh yes the seat belts are imperial, but the body to chassis? All m10.

Mine were M10, wasn't sure if they are all the same (handmade...?). The body tub bolts are a good place to upgrade to nicer SS.. whatever though IMHO

M10 x 30 IIRC. The body bolts aren't too bad as you can Dremmel them off is they seize. It's the seatbelt ones that made me nervous I took an awful lot of time getting them loose.

Thats why i asked about the sizes Spend thanks anyways part of the winter tidy up,among other things THANKS EVERYONE

Thought SS bolts were not a good idea on the body mounts or suspension mounts due to problem of them shearing?

They will burst out of the fibreglass well before any mechanical properties are reached IMHO. Not on the seatbelt fixings, just where the tub is bolted on was my criteria when replacing them (but again it was just as I got odd 'nice' ones like you do.. I really enjoy caressing my nuts in moments of thought - and strangely enough they are quite different even to touch )

Agreed,they are no way gonna reach there shear value even if you drove it into a tree at 140mph (on a private road of course) bloody hell Spend we have got to stop Agreeing with each other

Fair enough.......

For the body mounts if you want some nice big 10mm washers to spread the load I stumbled across some in Wickes the other day - biggest ones I've seen They were £1.49 for 6 I think.

[Chassis 33]

Right, just been out and measured the chassis...we're both right!!! The front end is M10 (transmission tunnel and front lower chassis). The bolts behind the fuel tank are 7/16UNF as are the seatbelt mounts.
