Bought the Ford Rotunda OTC tool kit on eBay for $230.us to remove and replace the rear crankshaft oil seal and slinger on my 05 GT when replacing the clutch. I did not want to fuck up that seal and so far so good.
I know what you mean,it would have been great to rent those tools somewhere . I also bought and still waiting for a used inner tie rod remover installer for $27.cad on eBay.Now I know who to bum for it whenever I need to do a seal swap
I wound up using the old seal and plank of wood and hammer to install my seal install my new block. Hoping it is fine and doesn't start leaking.
Also I just bought a caliper from amazon, it's annoying trying to guess sizes with a crappy tape measure or using drill bits for holes. It looks decent quality and seems to keep zero, it even can measure in fractions on top of decimals and mm
It's only 17 bucks and from amazon so I'm not to worried if it breaks. There's another brand listed at 21 regular 60.
