I did check again with Mike, and he said he cant supply unfortunately..
I pressed one out from the halfshaft this morning, and measured up:
-OEM Ford van MK2 stud :12.9mm knurl x 30mm length
- Nice brand NS bought previously NS 3400: 14.4mm x 73mm (nearly identical to Robbie ARP)
-S3800 stud:13.3mm knurl x 73mm.
I was hoping to fit studs to suit the new wheels, but may have to wait until an order is confirmed. Compomotive had said previously, that 15x8 ML's now only come in GP4 fitment, meaning they would need the collared adapter tube style nuts. I'm guessing that the standard studs currently fitted would still be too short anyhow to use these, 20mm of thread length seems short.
