Two atmospheres are better than one
It is. I was trying to be a little cheeky with my answer. “Yes and yes”. The torch (if oxy/acetylene) I would not use. It’s probably overkill for sheetmetal. Plasma yes though. And a cutoff wheel on a grinder is a definite yes.
Angle grinder with a cut off wheel. Or a sawzall depending on the cut.
Plasma cutter would be slick but I don’t have one.
Oxy/acetylene torch is a tad aggressive for this stuff

Everyone does fabrication differently, use what tools materials & skills you have...
End of the day whether you choose a five speed or a six speed you're gonna love it... The fun it brings to driving is a game changer...
In years past both my Challengers were automatics...I swapped out driving duties practically ever time I when for a drive... About a year ago I swapped a five speed into the red one.... Sorry to say, the green one is feeling pretty neglected

Well plasma cutters are cheap, so I’ll get one. I already have the crossmember so it’s can play with the parts car.
Did you do the tkx then?

I bought the T56 for my 69 dart still sitting in its box before the TKX was available. No regrets I've always wanted a 6 speed old muscle car.

I installed a TKO.... A buddy with a Cuda bought the TKO twenty plus years ago for a project... The car went through a lot of upgrades before it ever hit the road the first time... It only got driven about 500 miles... He built a much hotter engine than was the plan when the trans was chosen... He didn't like the ratios with the big horsepower, wanted a closer ratio trans... Bought the TKX & gave me the TKO for my labor in doing the swap....
I bought some parts from Silver State, machined some custom parts & installed a reproduction four speed bubble on my floor... With an E body I didn't need to modify the crossmember, just had to massage the floor some...
Plasma cutters are nice for a lot of jobs, but completely overkill for this job.... I mostly used a Harbor Freight air powered jigsaw....
The bulk of what I needed to do was add the floor hump..
I dropped it in place, traced around it, removed it, cut 1" inside the line, stitch welded the hump in, then from the bottom trimmed the flange closer to the hump... Then hammer & dollied the edge tight to the hump & stitch welded the bottom.. Finally I seam sealed the whole hump & painted everything to match...
After that a few test fitting, a little hammer work to massage in a little clearance & I was good to go..
Sounds like the A body requires quite bit more work...
the HF air body saw is what's up!
i love that stupid little thing. i use it constantly.
Nice friend.

I have the T56 Magnum with the 2.97 1st and the .64 OD ratio -> the car both performs better (accellerates in 1st like a 3.5:1 axle (assuming stock 2.66 4-speed) with 3.23's).
I have EFI and virtually any speed above 50 mph I can use 6th gear. Will pull a hill at 1400 rpm no problem. This is with a 340. My car has a sizeable cam and I did Power Tour 2025 with it, it is not at all tuned for economy and I averaged 19 mpg. The 6-speed itself was worth almost 2mpg when I'm in town and 4-5 on the highway with everything else being the same.
It also shifts great and if it ever needs repair parts it's almost completely a TR6060.
When I did the swap I used a "T56 swap" floor patch section for a Chevelle and cut and bent the floor to match. Mostly used a body saw and cut off tool.

When you're already cutting, just to the little extra work to get a T56 Magnum over a TKX. I would do it again in a heartbeat.

What patch panel is that?

Justin, do you already have a bell housing for the trans swap ?
