Porsche or VW flanges, 901 trans HELP!

[MartinH]

Hello everyone!

I have a question about the flanges on my Porsche 901 1969 transmission, they measure 4,3 inch, the problem is that they are hitting the framehorns. Could I replace these flanges with a VW beetle's? Are the diam. smaller on VW's? Or should I just notch down the framhorn a 1cm or so?

PLEASE HELP fast!!

Here is a picture:
