Hello Chodijnn,
Thank for compliment. Yes I have listed mine on Ebay due some changements in my project.
Alloy plate is very expensive (around 100GBP) and JED main studs kit also expensive. I have payed 127GBP with VAt just for 10 custom studs

. (no nut, washer and spacer). ARP extra long main stud kit would have been less expensive.
I am not in Europe at this moment, back only in January.
If you are always interested by alloy girdle plate, contact me at this time. I can made one for you.
Cheer.
Dimitri
