Outer Limits 4x4 Board

Hi Im trying to decide what diffs to put under a suzuki based buggy.I have the choice of 75 series diffs from a 94 model with the high pinion front diff or a set of 60 series diffs from a petrol model.Which ever diffs get used they with be fitted with longfields and upgraded hub bolts but id like to know what people would think would end up stronger out of the 2. The zook runs 38 inch swampers with commo v6 and twin transfers and is quite heavy. Any advice to help me decide would be appreciated

the rear diffs are going to be just about exactly the same in strength but the 60's frount is a larger and stronger diff than the 75 high pinion for reversing in 4wd underload.

im lead to believe 60s diffs are wider too

yes the 60 diffs are wider as i measured my 75 series and a 60 but I will also be putting wheel spacers on aswell and now the next thing is to decide what link setup to use
