I noticed on the Tom’s Import Toy Sales http://www.tomsimport.com/new/parts/parts.asp?sect=20&new=1 web site that he sells a nice replica of the factory tow hooks. They are made of high grade stainless steel and fasten to the car using the rear leaf spring bolt. I ordered a pair and was quite pleased with the quality. See images below:
Lin, I have a set of these tow hooks on my 67 Healey and also was very pleased with the quality of the product. Mick
