360 Tow hook not fitting.

I bought one off a 360 from a wanker who said it would work in my 430, it didn't.....

I replaced mine on a 430 and initially wound not fit, turned out thread in the frame needed a thread tap down to clean it out. The tap is a metric fine thread

 

I took a lot out off the female thread to make it fit. I thing they make in 15 mm size anyway. But a 16 mm fine tap

 

This works on the 360.
I have it installed on my car
360 is M16

Did you look at the link ? 1.5

 

In case the tow hook was original 360 part (155838) it should work.

M16x1.5 bolt/male has about 14mm diameter at the bottom of thread and 16mm diameter at the top of thread.

Potentially overkill procedure but something I like to do with clogged internal threads:

1) Start cleaning of the hole spraying some rust-off products and follow with a cylindrical metallic brush.

2) After that apply liberally some lubricant, eg. WD40 or similar and use carefully appropriate threading tap, in this case M16 x 1.5

3) Thread in the intended bolt, the tow hook in this case. In case of tow hook hole, you might want to put in some anti seize and cover it to prevent it to get clogged again.

 

Use WD40 and some of these

It’s a 1.5 mm thread- that is what I meant by a fine thread. A normal thread is a metric course
Be sure you get a plug tap and not one of taper type

 

It needs a tap and it be fine
