951 Belt Cover Modification (WP update)

[philcav7]

I am updating the water pump on a 86 951 and need to know how to properly modify the rear belt cover to accommodate the new pump and guide rail.

Does anyone have detailed information or pictures outlining what needs to be done? Before and after pictures would be great. Or does anyone have an 87+ set of belt covers laying around that they want to get rid of?

Thanks
