Oil filter relocation adapter.
If thinking about using a factory MoPar 90 degree adapter the 273 ones are a true 90, 340 ones have a slight angle to clear the dipstick tube on the 727…273 used a 904 and the tube wasn’t as close…I would find a 273 adapter. I’ve seen several on Facebook for sale and eBay… I’ll see if I can remember the correct part number for you.
