Sorry Steve, can't help you on the yoke. I'd also like to know about this, are you planning on buying a new one or going the junk yard route? Are the 60 yokes pretty much interchangeable?
If you haven't done so, you may want to look into up grading the cv on the front driveshaft as well. I was made aware last weekend that the cv joint was the weak link in my front driveline. Went camping Saturday night and was spinning the Swampers in the snow (still moving though) at around 4000 rpm in first gear 4-low. My best guess is that one of the front tires found something solid. Stopped me dead in my tracks, made a pretty interesting noise though. Sheared the ears right off the top joint. Haven't got a chance to see if it's fixable or not.
