I just installed one also and no issues. I had to dig up my windage tray nuts that came with my arp kit as my previous pan (Holley 302-1) had a pickup with a single support. Mast has two.
Happy with how it all went together and I did opt for basically every option they had (dipstick and tube, oil cooler, etc)
The pan has some casting flaws I'm not thrilled about but it will be fully functional. Also I wish the port on the back has more space for a sensor or fitting. And drawing of that needs to be updated as the thread identified in the drawing is incorrect.
