I know some that made a spool themselves back in the days and got it to last a long time in a 360 duster stocker...but it finally gave in and had to leave room for a 8.75..the gear selection isn't very good...a 4.56 looks like "top of the line"!

yea Richmond has a part number but they stopped making them, told us we need an order of $10k to get a set, oh well Jim Baileys stuff has held up better then anything i have ever bought from Richmond. Also the 8.75 rear is great if its set up correctly i've been 10.7's @ 3200+ lbs and no prob with the rear just the richmond street gears.

Bob, No I am not going to use the 8 1/4 behind the hemi. This question is for the slant six wagon. I have a garage full of spare parts for any rear axle I use I'm just wondering if I will gain any ET by putting a 8 3/4 under the wagon, The strengh is not in question.

So is a 8 3/4 faster than a 8 1/4? anybody have a real answer?
