front top strut mount location!!

[Reddog929]

I cut the front of my 1971 240 off, built a frame and now need to locate the location and angles of the top strut mount we are going to fabricate. I placed a photo in my album called strut mount (reddog929) take a look and you will see what I need. I have the lean in angle of 13* 54'. Looking at the old front end the mount also leans back to the fire wall, might be around 5-10 deg. The front cross member is in the correct location and bolted on. Also need the hight from the frame to center of mount. I think its close to 16". Any help would be great Thanks

Had a look in the workshop manual? IIRC the factory manual has key chassis measurement info. Link to the photo?

But if it was mine I'd be looking at changing the stock strut mount location, particularly with a competition car. More negative camber, castor?

I have the camber angle. Look at the top mount it also is angled back to the firewall. This one I do not have. We took a plasma cutter and cut the car off at the fire wall. Can you get a measurment from your 260? How far is it from the firewall to the shock center hole? How high from the frame to the same location. Do you race you 260?

Reddog, here is a photo. No angle in the direction you seek is given. I would assume it is 90 degrees to the shock rod angle.

Mine measures ~520mm from the strut tower middle hole back to the adjustable bonnet support bolt hole, there is one of those on both sides.

From the top of the bottom rail to the top of the strut tower middle hole is ~405mm.

Avatar car is mostly used for race circuit work and driving to and from, love it

Were would you mount the strut. As you can see (my photo's) this is a good time to set it up the correct way. What is the adjustable bonnet. Control arm mount? From the manual drawing all the measurements are from the frunt sway bar mount. With the new frame rail I do not have the location of the swaybar bolt locations or the control arm location. I know that my cross member is in the correct location so all I need would be the measurement from the crossmember bolts to the swaybar mount bolts and the same distance from the crossmember to the control arm rear mount location.
