328 Door check strap mechanism

Hi this is my first post, having had my 1986 328 GTS for three months! The driver's door check strap makes two loud cracking noises each time opened or closed. It is the mechanism, not the roll pin at the door. At the mechanism, the arm moves a little vertically each time it cracks. I have a NOS replacement mechanism, and would like some guidance as to how to replace. Seems like there is a cover held by two screws to access the whole area but the two door position electrical sensors may cause complication? Or is there access from the wheel well? Is it necessary to remove the door? This would be my first non trivial job on the car so I'm a little nervous, although I have lots of experience on my other toys (BMW M3, old Ford Mustangs etc) and a well-equiped garage. Appreciate any guidance.

 

Yes good suggestion. However the nearest "Ferrari mechanic" is 500 km away. There are two 328's in Chile, and one 308, as far as I know,

 

Thank you very much!!

 

Thank you, I think the door is OK but will check carefully, hopefully I will get to do the job this coming weekend.

 

I found it on https://www.ebay.co.uk/str/schlaunach

 

By the way, I suggest before laying out a wad of cash, knock out the roll pin at the door and see whether it is intact over its full length, and also take off the panel (two screws) far enough to see whether the two check strap assembly attachment nuts are tight.
