Auto to manual conversion

thank you, maybe I'll just go with a shift kit for now
You know I was just busting your seeds with that first comment LOL.
You shouldn't have to weld in the floor hump. I didn't when I did the conversion on mine actually it works better to just put some glue down window sealer and screw it down as it makes a great access door when doing other modifications. When I take my engine in and out or my transmission and out it's nice to just be able to reach in from the driver's seat area and undo the top bolts to the transmission to the bell housing.
Like mentioned that whole for the z bar pivot in the frame needs a backing plate but those are sold as well and it should be located already on your car... I would think the pivotal and nuts would hold it in place at least long enough to get it to a muffler shop for them to toss a couple small welds on it.. of course I have my $89 Harbor Freight welder and really it's just a matter of sticking the gun up there and squeezing the trigger...
There's a lot of people locally selling the parts for all this stuff some of them are a little crazy and some of them are reasonable...
If you go with a shift kit that's a nice option as well and you can even get a stage 3 trans go where you have to manually shift it. In that case I would get a nice shifter though.. my preference is always the Quicksilver b&m shifter, as it's a nice ratchet shifter...
