Spare wheel well mount bracket measurements

[Wladek]

Hello everyone,
spare wheel well in my car is new & wheel mount bracket is missing - can somebody help me & give dimensions of that part?
I don't like how W&N mount is made, so i am considering making my own.
I need:
1. Lower diameter of the base (without ears that are welded to the floor)
2. Upper diameter of the base
3. Height of the base
4. Bolt height from the top edge of the base
5. Bolt size (diameter)

Thank you!

No one???

If your car is an E3 or if yours is an E9 but they are the same as an E3, I can measure my E3 for you.

Here you go:

1. Lower diameter of the base (without ears that are welded to the floor) 65mm
2. Upper diameter of the base 60.5mm
3. Height of the base 105mm (measured over the ears)
4. Bolt height from the top edge of the base 65mm
5. Bolt size (diameter) 11.85mm (same as wheel lug - M12)

Hi Wladek, i have mine chopped out from the spare wheel well, so i can measure other things if needed easily.

I first purchased the walloth part as well, and when i recieved it i ditched it. Wrong diameter pin and slightly different shape. (Also the case with the towing hook)
I choose to patch mine and weld new feet to it.

Thank you Eric - actually dimensions of genuine towing hook might be helpful for me, i also don't have it.
When W&N introduced this parts - straight angles of towing hook rejected me, because genuine towing hook was rather rounded shape. Same with spare wheel bracket - that ugly cutout in a middle.

Perfect! Here we go:
Overall length 180 mm
Width at base before cutting off the corners 112 mm
Width at mid circle 90mm
Circle , inner diameter 52 mm
Circle , on average 19 mm, it is more 18.5 to the sides, 19.5 at the top.
From top to foldline 95mm
Two corners at the bottom 17 by 20, but i shaved them to get rid of edge rust so they could have been 15 by 18 or so.
Angle 162 degrees

1st pic, Side view shows how it reduces gradually from 13 to 5 mm, where it folds flat.
2nd. Edge, but also the inner ring are 9mm high (or thick)
Third pic same 9mm but differently measured
4rth. Inner circle; the edge folds over by 5 mm, . In cross section this curve starts with a quarter circle, then the radius is larger for the orther quarter: the last bit is. mmore like a cone.
5.Outer edge folds over by 7 mm
6.The outer edge, in cross section is a pretty nice half circle, but quite bumpy /wavy due to the folding as can be seen from the side pic.
Pic 7& 8& 9 : To better be able to lay out the flat sheet, i measured the 'length' of the metal that forms the outer radius. From the somewhat difficult to define flat line to the inside is 13 mm.
10.Last pic shows 12 mm for the length of the inner curve.

Ps sorry for the long and detailed answer, but your question was my excuse to sneak to the garage; from a too boring tv show on the couch next to ' THE SIGNIFICANT OTHER'
