Top man Paul, that explains very well, so my 110 has these
FRC6137 M16 x 1.5mm x 39mm Defender to (V) KA930455 (Disc/Drum)
& these are the other set of 20 I've got [but there mot XD/Wolf as I thought]
FRC5926 M16 x 1.5mm x 39mm Defender from (V) LA930456 to (V) 2A631135 (Disc/Disc
Ralph, that's correct, except that most (if not, all) Wolf XD have
FRC5926 fitted
My 110 (FA model year, same as yours) has
FRC6137, I made the mistake of thinking that
FRC5926 would be longer - they're not, they're identical

- fortunately, I only bought a box of 5, which I've since used for other things.
FRC7577 isn't in EPC or Microcat, but it came up on my Dealer's parts enquiry computer as fitted to - Defender XD, Heavy Duty 110/130 and Armoured Applications, it also came up with £8.00 + VAT each

- that was a couple (or so) years ago, and I now believe that they're about £15.00 + VAT each
Paddock's are selling the Britpart version of
FRC7577 for £1.82 +VAT each (Tony passed-on that tip in his 'Longer Studs/Stazworks Wheel' thread that he's linked to earlier in this thread)
I bought a set of 20, back in August, which came to £48.65 incl. Carriage & VAT
To the best of my knowledge,
NO Wolf XD's, HD 110/130's have left the factory with
FRC7577 fitted.
As these studs are 15mm longer than the standard studs, I suspect that they've only ever been factory fitted to Armoured vehicles, fitted with non-standard HD/Run-Flat wheel rims, but I've never been able to get near enough to one with my Vernier Calipers
The later part numbered studs AFAIK are dimensionally identical and interchangeable with the earlier part numbered studs.
Paul.
