Real Racing 3 .points files

I'm converting Real Racing 3 cars, and I need a new way of figuring out where the wheels are positioned. I found a file with ".points" appended to it. When I look inside this file's data, it has the name of the wheel dummy. After that is short garbled data that I can't seem to understand. The headlight dummies have scale to them. Is there a way to convert this into a text file or something?
Note that I use the 3D modelling program Blender. If scripts get made for another program to solve my problem, then it will not be useful to me.

You wouldn't expect someone digging into a .points file without having the belonging model file, do you?

So it's for the wheels? Problem is, there's LOD_A_STEERING_WHEEL_mm_cab in the model file
and POINT_WHEEL_BL, POINT_WHEEL_BR, POINT_WHEEL_FR, POINT_WHEEL_FL in the points file.
But none of them is in both.
(At least not from the ASCII names. Maybe they're referenced via hash, too, dunno.)
(well, and didn't find the 4 wheels' mesh in the model file)

yeah, ok, but they're in place!? So we'd need some hint in the .points file for the misplaced
steering wheel to get it's position offset, correct?
Maybe I didn't get what you meant with this:

I meant that I use the LOD_F wheel model to figure out where the wheels are positioned. Sometimes it does it wrong tho. The LOD_F has its wheels in place. The LOD_A wheel is like the steering wheel, it's not fixed in place. We do need a hint in the points file for the steering wheel. I'm sure there's some sort of order in there that defines the point's position.

ok, are you familiar with floating point IEEE754 format? You'll need to understand at least where a coordinate component starts.
I load
1993_alfa_romeo_155_v6_ti.points into hex2obj to give you the idea (any hex editor capable of showing floats should do, too).
Here we go:

You need to
vary the start addresses 'till you get some meaningful position.
Positioning the steering wheel manually in your 3D app may help to give an idea for which values to search for.
Seems we got a matrix (well, broken a little bit
), so there's rotation and position x,y,z: -9.578007 -67.851753 12.298819.
But for which part?
Maybe TRANSFORM_EXHAUST_02 (or _03)?
(Seems there's too many parts and too less matrices in that points file?)

Where can I find hex2obj? I remember having it on my computer, but I don't know where it went. The link to the download doesn't seem like it ever existed! Searching "uploadmb" on google returns nothing!

View link in my sig or here
But it's a quick workaround only. A capable hex editor (with "data inspector") would do better, I guess.
(Can't tell which, because for me it's easier to just write some C code for tasks like this one.)

Yeah, strange. I'll create a temporary post for download 'till I find a new file hoster.

I'm thinking of returning to ripping RR3 again...but not until I got this file format solved.
