I've had a look to see if this is mentioned elsewhere, but I can't find anything. The attached photo is of one of the clips, I think they're known as 'captive clips/nuts, from the subframe, holding the rear of the engine undertray. There are 3 of these and only one is still intact (just). Could anyone offer advice as to where I could get some replacements, or similar items that would serve the same purpose? Thanks.
