Default 4 Speed Borg Warner T-10 Overdrive

I have a 78 L-82 4 Speed and would like to keep the stock transmission but would like more overdrive gears. I am not interested in switching to the 5 speed transmissions from Keisler etc. I would be interested if anyone knows if there is a company or kit that changes the stcok gears in the T-10 four speed so that 3rd would be 1:1 and fourth could be on overdrive such as .64:1 or or less. I have 3.70 rear gears and of course could changes these to 2.73's as another option but would lose some acceleration doing that change. I just want to change the gear box ratios.

I'll check it out but I'm really looking to keep everything stock looking and just changing the Borg Warner T-10 internals. The prices for the aftermarket 5-speed transmissions are way too high. Changing the internal gears would be a fraction of the cost of the 5-speeds and ultimately achieve the same result. Many times when driving I shift from 1st to 3rd/4th or 2nd to 4th since the engine has more thaN enough power for this skipping with very high RPM as geared from the factory. I really would like to switch 3rd to a 1:1 and fourth to a steep overdrive.
