What kind of finish is this? Black phosphate bolts, looks like silver cad on the washers If your buying reproduction hardware, No matter who from. THEY ALL come from AMK Are they truly OE correct for every car??? , absolutely not. But short of buying used , they are the only game in town As for the OP , I know for sure the original lower bolts were different length and dont remember head markings 100% ( hell to get old ) But the best I can remember they were different side to side and were not the same as the 3/8" ones along the upper perimeter of the bell hsg

What kind of finish is this? I've own, race and work on a bunch of original 4 speed and automatic BB cars from 1962 to 1970, none of them had star flat lock washers from the factory on the engines or trannys, NONE of them
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Almost definitely sure they used the same bolts auto or manual. And all had the captive washers (bolts threaded the whole length)

Cudaman, Your not correct. The cast bell house used what is shown. Measure your bellhousing bolt hole thickness 4spd or auto. The hole above the starter has a much thicker area requiring a longer 3/8" bolt. The 727 used the captured washers style with the cup ridge on the head fully threaded, not the same for a 4spd in a cast bellhousing. Now 71 up where aluminum bell house used I am not sure. Here is the tooth washer that was used on the bolts that mated transmission to bell house (NOT bellhousing to block). I have seen them on cast 4 speed bolts. That transmission bolt is another style also. Too much of anything will work, and folks mismatched stuff in the day. But we are talking about three different bolts right now. Auto to block, bellhouse to block, and 4spd trans to bellhousing. All three are different styles bolts and washers at least 70 and down.
If you use a shorter 3/8 bolt (1 1/4) in that hole above the starter you have insufficient thread to meet design criteria for thread engagement in a blind cast iron hole and you risk pulling threads out of the block if you over torque it.. Has been 40+ years since the stick bellhousing takeoff but I can’t remember any star washers. I do have an aluminum 70 Hemi bell I’ll check for hole thickness later. The hole above starter is deeper but all had captive washers, no stars marks on any hole. Could see the paint circles

Here are the original bellhousing to block bolts from a ‘70 V code cuda (B18 SPD). Are you claiming these are used on all manual trans bell housing?
