Okay now look at this crossmember part number D1ZZ-6A023-B
It's unique in that it has 3 center mounting holes and a center reinforced plate
Perogie has one for sale and says it's specific to the 7173 Stang w/ 4sp toploader. 429Megasite also says this part number crossmember is for the 71Mustang, but they don't have a picture of it and only a drawing like Roys but the drawing shows a 2 hole crossmember like the ones used on the 1967-70 stangs.
I was told by a few now that the correct crossmember are in fact the ones used on the 67-70 so who's using this 2 holed crossmember and can confirm for sure which is the correct application for a 4sp toploader, 351C equipped 1971 Mustang?
