So what ones do you want, 800 or 810?
Also how many do you want, 16 or 20?
Do you also require the lug nut socket?
Are you fitting these to LMGT4 wheels?
The solution is to use preassembly grease.
There are circa 80 x 6mm similar bolts on the R35 GT-R undertray panels and every time I have them off I always re-grease them which is very time consuming but well worth it.
In all fairness, I think it could be up to 4 weeks before I start to dismantle this car I am afraid.
However I can remove parts now that does not compromise me starting and moving the car about the shop.
Unfortunately that does not sound healthy Chris, and a replacement engine may be required I am afraid.
How is the engine oil level?
Low mileage preowned engines are in stock if required and ready to ship same/next day.
