Wheel nuts different front to back

[Simon Waterfall Syman84]

I have just put a new set of wheels on the old girl and thought I would treat her to a new set of wheel nuts so ordered a set of Cortina alloy wheel nuts the ones with the built in chamfered washer for ford alloys.M12

changed the fronts no problems came to change the rears and the nuts don't fit looked at the difference and you can visibly see the difference and look to be smaller does anyone know what fittings are and where I could get some from

capri gt back axel

thanks simon

Smaller diameter or length? Found my rears were alot longer so the captive wheel nuts didn't tighten up.

^{I only know of two types   ones with washers like the capri lazer type  which have a bigger hole or std ones. but they can come in smaller size spanner some are 17mm and some 19mm/}

sorry smaller diameter I thought it was me being silly but I tried the front on the back and the back on the front different thread so for time being I have just used old ones on the back maybe someone can have a look with me at the factory visit on Saturday

might be imperial and metric

Pete just had a look around and I think you are right they look like they will be 7/16 on the back and m12 on fronts

Quite possible for it to be different front and rear as the front uprights would have been sourced from a different car to the back axle. Assuming they are Ford, then they changed from 7/16" UNF to M12x1.5 in the mid 1970's. It is easy to change from imperial to metric, or back as the studs are interchangeable. Knock the old studs out of the hubs and draw the new ones in. Should be possible to do it in situ as long as the new studs are not too long.

Easier to change the fronts than the rears.
