The dealer will sell only the entire push rod that includes the ball cap (they replaced the red ones with white ones that apparently are more resistant to cracking): http://e-partssales.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=P&Product_Code=98656127902&Category_Code=986top

Or, you can buy just the ball caps from a seller on ebay. This guy sells just the 2 ball caps for around $42 bucks: http://cgi.ebay.com/ebaymotors/Porsche-plastic-cap-2-Top-push-rod-boxster-986-987_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1205Q7c66Q3a2 Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1318Q7c301Q3a1Q7c293Q3 a1Q7c294Q3a50QQ_trksidZp3286Q2ec0Q2em14QQhashZitem 2c4f0d3edeQQitemZ190304829150QQptZMotorsQ5fCarQ5fT ruckQ5fPartsQ5fAccessories
