If the pictures are anything to go by, the iPd one has the plastic preload plug that the original and reman racks have. The other three links have what look like steel plugs. So not the same product at iPd unless they just used whatever pictures they already had. The tube is also painted black.Right on....
I wonder then....probably the one they've got over at IPD is a CVI too. I also wonder if it's worth the gamble. It'd get here the quickest, and it's ~$60 cheaper...
IPD: $475 + $79
CVI: $453 + $159
CVR: $666 +$56
VP Auto: $666 + $76
Then again...what's a 'gamble' when you drive the car less than 1,000 miles a year?
