I’m obviously an old romantic as the Singer “look” doesn’t appeal to me at all. I get backdating as people want the vintage look but whilst a Singer is loosely based on a long hood, they are a completely modern interpretation - nothing authentically vintage about them. There are a heap of companies out there doing backdate jobbies and the more successful examples look actually like something authentically Porsche, not something that so obviously screams backdate like any Singer tribute does.
A 74 chrome hoop targa sounds super peachy. Spend your $$$ on stuff that will make it drive better, embrace the early g narrow body goodness. Impact bumpers are rad. The more research you do into Porsches the more you’ll hopefully see what is out there and Singers aren’t the be all end all.
Any bearing supplier can get them. They are a common size. You can see the part numbers on the pelican site if you cant see them on your actual bearings. You could buy from Pelican but we should support or local businesses with simple stuff like bearings.
