Ok, so I have an 77 SII and a pair of 3/4 ton axles of a GM truck, they are a D44 front and 14bolt FF rear, eight lug of course. I did a search on this setup but was very vague, how about the guys that have made this work? Some tips and tricks would be very nice right now...Pix would be awesome. Supposedly the gear ratio is 4.10, havent popped the cover(s) to verify yet but my plans are to run some 39's max, only if the ratio is ok with this tire size. The SII is equipped with a t19w so i see no trouble there yet. Input?
