they are the hedmans http://cgi.ebay.com/ebaymotors/New-...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories and jegs/summit have them for less.
yes they do... http://www.jegs.com/i/Hedman/500/88400/10002/-1 $153.99 http://www.summitracing.com/parts/HED-88400/ $159.99
The Hedman headers use a flange - the ones the OPshowed had a ball joint for the pipes - not a flange.
if you go to the ebay link you'll see its the hedmans.... http://cgi.ebay.com/ebaymotors/New-...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories the ebay seller probably just buys them and resales them for a higher price. and like most sellers they just use a generic pic. look at the ad [SIZE=-2]"Fit standard 429-460 heads only. " [/SIZE][SIZE=-2]"Due to engine location, will not fit 1970-72 Cutlass Supreme, Hurst, SX or Convertibles.[/SIZE] i doubt that the ones he'll sell you will have a ball joint...
info like this is why i ask. but checking these links both list falcon,fairlane,mustang and mercury cougar no mention of the Maverick for the 88400 but price is a lot better! hope no one buys from this fella trying to make a buck sittin on his A$$
