I have a MK10/G250 set up as a stage reg with a brass SPG, but here is what makes this deal special. It includes 4 pistons, 5 springs, 16 MK10 rebuild kits, and 2 MK10+ kits. It can be difficult to find MK10 parts,so there is enough stuff to keep all your stuff functioning for years to come. $250 for all plus shipping CONUS. Best to email me at cavedvr@yahoo.com since I don't check here often.
