Default TRS Bellhousing studs

Anyone know the correct diameter/thread pitch for the studs the mount the drive to the bellhousing? My steering plates mount over these, so I need longer ones than stock. About 1/2 inch longer. Tried latham, no luck.

The threads that screw into the bell housing are 1/2"-13 NC and the threads which are used for the nuts that hold the drive on are 1/2"-20 NF.Total length of the stud is 3 1/2" with 1 3/8" of unthreaded area in the center.

I got mine even for the #4 at ARP ,,,for a fraction of the merc price. I paid like 6 bucks each and mercc whanted 76 bucks each.

Just call and tell them length diameter and thread sizes.
Also how much non threadet erea in the center and they match it up ,,,plus there studs are even stronger .
