It appears to be PP833 29 8 263. There is big space between the the 9 and 8. The 0 is stamped there so it may have covered it up. It is in a clone 69 six pack Bee now and I have been employed to change out the gears to Passom OD set. I doubt it could be bought but someone may be looking for their transmission. I wish someone kept a big list of lost and found blocks and transmission. I have several Hemi 4 speeds
