I just don't trust a D35 axle for more than anything other than a paperweight and putting money into it is one of the silliest things you can do. YYMV.
From this past weekend, open/open D30/D35 on 33s. My buddy didn't quite make it obviously.
I ran 35" Dick Cepek crushers up until last year on a D30/Ford 8.8 setup. Locked front and rear, stock shafts in the 8.8 and chromo shafts in the D30 with 4.10 gears. My crawl ratio suffered a bit compared to guys running 4.88s, however I had the stronger ring and pinion setup.
So that being said, you can easily do an 8.8 axle swap for the money that you're looking into putting into your D35 with the ARB and Super 35 kit.
