I found a set of torque bits on Ebay for $5.00 free shipping that will cover this repair- includes T3-T8 torque bit screwdrivers. However, the best quality one that I own is from LOWES- brand is kobalt model # 239384 and price was $6.98 at my local LOWES. Its one screwdriver small with rubber grips that has a holster in the handle that you pull out to reveal bits T4-T10 (the T4 bit is small and will fit T4 and T3- I've always used it for T3 with no issues), and you can grab the one you need and pop the bit in the torque screwdriver for whatever project your working on.
