Rear end dimensions?

Don't want to crawl under my truck with a measuring tape with all the snow/slush/mud in my driveway so I thought I would ask if anyone knew the axle flange to flange and spring pad centerline dimensions for a 94 ext cab 1/2 ton 2WD.

Re: Rear end dimensions?

Thanks guys. Been thinking about swapping in a 1969 Ford F250 Dana 60 I've got on hand. I'll have to change wheels and maybe carry two spares but the extra strength and a little stiffer gear(3.55 vs 3.42) should be better for towing the race car trailer especially with all the miles(and hills) we tow over the race season. I'm getting tired of damaging those stock 8.5 rearends.
