Yes, they come with both the cap and nut. Last Thursday afternoon I emailed Nick at FCPGroton an order for two Bilstein TC (touring car, economy as you call them) front strut inserts for my 760 Turbo, to be mailed USPS to my POB in the mountains of Puerto Rico. I got them this Monday morning despite the holiday weekend, $90 plus $15 shipping total! I had them put in the car Monday afternoon to replace new Boge Turbo Gas because one of these had failed with only a few thousand miles. Bilstein TC are a bit firmer than Boge TG as Nick had said, but as soon as they were on the car the Bilstein seemed to give a lot better handling than the Boge. The car is a pleasure to drive. I found out about FCPGroton from Don Foster here at Brickboard a few years ago and since then Nick has consistently supplied me with the best parts at the lowest prices with the best service. I think he likes doing business with Bricksters. Order your strut inserts, Nick will do right by you.
