Pleased to see that you have reached this huge milesone mate
There are plenty of new wheel studs available .... I guess this is the sort of thing you'll need to find
Ford Wheel Studs
Just make sure you get metric ones though.
I normally support the hub on the corner of my very large vice & give them an almighty twat with a club hammer ( Hitting it hard & square is the trick )
If you dont fancy that job, I am sure that a local garage or engineering shop will press them out for you.
I usually pull the new ones in with a couple of washers & a wheel nut .... Grease the washers, place over the stud & then do the wheel nut up so as it pulls the new stud home ( Wheel nut flatside toward the hub )
Sometimes you'll find them very tight, if so, it is probably best to have them pressed out.
Well done on your progress so far & look forward to watching the rest of the build come together
