901 to 915 transaxle swap in 1967 912/911’s

Ok guys and gals, I have a question for those of you with much more knowledge about this that I have.

I have a 1967 911 (born as a 912) with a freshly rebuilt 2.7L out of a 1976 911S. My current 901 has customized gear ratios, which I no longer like, and is in need of rebuild. Many years ago, when I rebuilt that 901 transaxle, I used to regularly take 500-1000 mile road trips and had a long ratio transmission built for for top speed driving from San Diego to Las Vegas as well as a super low granny gear to handle stop and start driving on steep San Francisco hills. Now I have other cars for that kind of driving and want a more traditional gear ration set up. Because I have the bigger motor, I am planning on putting a 915 transaxle with LSD and light weight clutch assembly (both of which I already own) to better handle the additional horse power.

I know that there will be some metal work required to fit it in. Does anyone have a diagram or pictures of where the metal will need to be worked?

Also, I need to replace one (possibly both) of my rear seat pans due to rust. Because of the transaxle change could I solve the metal bending problems by installing later seat pans with, I am assuming, a higher hump in the middle? I.E. Would a later set of seat pans fit right in and solve my metal bending problems?

Any words of wisdom would be greatly appreciated…
