Driveshaft safety loop mountinh

[bigrozz]

I've made some driveshaft loops but would like to clarify the mounting on the top side, I have 2 M12 bolts going through 2 seperate 50x50x6mm washers inside the car on either side of the driveshaft tunnel, just wondering if it is suitable or if I'm wasting my time.

Drive-shaft safety-loops attached to a vehicle floor must use one doubler plate on each side of the driveshaft
safety-loop with a minimum mating area of 3000 square mm. All doubler plates must be mounted
as closely to square as practically achievable, have all corners rounded to a radius of no less than 5 mm,
and have all edges which contact the vehicle structure to which the doubler plate attaches rounded by
the removal of no less than 0.1 mm of material. Where the mounting surface area of the drive-shaft loop
is less than 3000 square mm, an additional doubler plate attached to the underside of the floor must be
used.
Note 1: A typical plate size that meets the 3000 square mm requirement would be a 50 x 60 x 3 mm plate
or larger.
Note 2: When a pair of doubler plates are used, it is recommended they be riveted together.

That is from our updated driveshaft safety loop infosheet, so maybe have a read through that.

Whoops, forgot the link!

That wording is on the start of page 3.
