I would like to buy these springs but i have possibly a stupid quetion..... How can i tell if i already have them???? I told you it was stupid. I ask this because the PO has done many of the usual upgrades that many People do to mustangs. He also managed to mess alot of things up too but we won't go into that. alot of the front end was replaced I can tell the 35 year old parts from the newer parts but the springs don't look new but they don't look like they are 35+ either. I was thinking I could remove the springs and measure them but thats alot of work if i already have them. Any Ideas?? TIA

the numbers were engraved into my 620 springs. i believe they were put on the top of the spring. that would require you to pull it out. but there is another difference with the stock and the 620's. mine is powder coated and much thicker. i have no idea if lower or higher spring rates are powder coated also. so i think you're going to have to pull them out to be sure.

When i push down on my front it only goes down about a inch. I weigh over 200lbs. I have 620's, with
the stock spring I could push the front down 3 or 4 inches. What I'm getting at here is the 620 rate springs
are very stiff. How the handleing of the car now?

Don't really have a good answer for you on the springs, I don't think that's a dumb question either. From what I've read in springs from past posts is that each manufacture have different ways for what they call 620 springs, meaning that 620 springs from 2 different manufactures could have two compleatly different spring rates. I seem to recall that a few people who have bought 620 springs from Canadian Mustang actually had lower spring rates than stock springs. I can't say one way or another if it's true. This also was from past posts, take it for face value. If you have any doubts, way not buy a new, known, pair of 620's?

BTW, I like the blue on your fastback, what color/name and metalic or not, thanks.

Thanx, What I'm probably going to do since i'm on a tight buget right now and I just bought a new house is wait untill i can rebuild the entire front end and then I'll slap the 620's in. It's fine now how it is mechanicly wise, Just ugly.
I like the blue also but it's deffinatly a 20 footer, I have a Digital camera in the mail know and when i get it I'll snap some current pics with the new crager S/S's Installed. I really don't now what the color is called, I have a can that came with the car but the label is too faded to read. All i can make out is PPG acrylic Enammel......... When I repaint it when everthing else is done I'm probably going to go with a darker Midnight blue or dark green. It was originaly "Silver-blue" But it's far from original so thats not an issue anymore....

I believe the numbers "620" should be engraved on the top of the coils. In my case, for 69-70 cars, "720" was engraved in the Magna coils.
