39 chevy core support

have a 1939 chevy frame with Fatman Mustang II IFS on it. Ineed to locate exactly where the radiator core support is supposed to sit. I called Fatman and they couldn't tell me even though they sold it to me. Help!

It's best to build a birdcage fixture out of light tubing, or conduit that bolts to fixed points on the fire wall and to fixed locations on the radiator support before cutting off the frame > if you can find another car that is together take a lot of measurements use level. etc. then set it up. 50 years ago in my auto body class my brother and I rebuilt a front end crash, then brought in a new hood. the instructor said if it would fit with out having to move fenders and things around we would get an A . We had measured a good car and the hood fit perfectly.

Thanks for the help. Here is the big problem, the body is on saw horses, the factory core support was already removed when I bought the car. The Fatman kit has a replacement core support that you must locate and weld in. When I called them they couldn't tell me where to locate their own product. The birdcage idea is spot on if I can get the core support centerline dimension. If this wasn't so crucial I would SWAG it. I appreciate your help.

Sometimes we just have to bite the bullet and do it the hard way; put the body on the frame and situate it where it sits corectly and make the measurements. It's a pain, but necessary evil.
Can't tell you how many times I've had to put things together multiple times just to ensure I got the fit where I wanted it. Always a little frustrating until it's together the last time!

As stated above, you will need to have the body back on the frame. Then its fairly easy. Mount the inner fenders to the cowl- you will need to cut them out to clear the a-arms. This will give you the reference point you need since the radiator shell support attaches to the inner fenders.

Retsfc7, are you talking about the support that mounts to the frame?

Yes, like the one in the picture.

It looks like yours bolts to exhisting frame holes. Mine is welded to the bottom of the frame. The diminsion I need is from the longest point on the front of the frame to the centerline of the support. Yours may be 4" wide, and mine may be 3" wide and a totally different style but, if I have the measurement to centerline of the support I can square it to the frame and get it welded in ... without setting the body back on. Hope this makes sense, thanks for the help.

Retsfc7, that measurement is 7 7/16 " . I would get it located tack weld it, then when you get the body back on and everything checks out then weld it in. Spanky
