The rear presented little challenge, I made a steel loop out of 4mm sheet with the plasma cutter. And cut a hole with a Rotabroach (Mag Drill / annular cutter) the appropriate size, enough to leave sufficient strength in the loop.
The front presented a bigger challenge. I needed something that attached to the chassis but avoided fouling the front bonnet/hood while accessing while opening and closing it (refuelling etc).
For the front I obtained a MSA compliant adjustable towing loop that extends beyond the GRP bonnet/hood and clips on to it with a press stud. The adjustable nature of the front tow loop locks in place once bolted to the attachment point.
The attachment points needed MIG welded to the chassis although I am sure a non welded solution is possible. Much time was spent restoring the chassis paint.
This is the second time I have had to attach something to the chassis post build.
