I want to thank you all for your interest.I would have went to summit today but they are closed and if they have the .021 in stock at Talmage,Ohio store
I drove to summit and got the .021 and got the bell to read from .001 to .007 so I am good to go when the trans is done.I will update when I get the trans.

I go to pick up my trans tomorrow and he insists on putting on the bell to the trans for correct sealing to the pump.I waited to order a Vert to be sure nothing went wrong with my order on the trans so I can now order that and get moving on the mount and driveshaft.

After he mounts the bell I am going to ask him to put in a converter so I can check the depth of the vert pilot to the engine side of the bell.

JW said to ship the bell back.I went to rossler and he let me take a REID bell and another to test fit and so the factory dowels are too big for both bells and I hope to have a buddy turn them down .002/3 tonight after he is off work and then I can test fit what rossler lent me.

I think it will be around 58".I would have got a longer tail if there were better communication with the builder.The 727 is 35" th400 is 28" ps:I ordered a PTC 9.5" converter will be here in 3 or 4 wks

how tall is it in the back from the mount point to the top? Interested in comparing it to a Nag1 and TF8 I have to see how much cross member surgery I might need.
Thanks

In the trans cross member pic the trans is topped out just to test fit and is just above the trans cross member ledge 3/4" maybe.

The trans and engine are test fit so I can make a trans mount but the input shaft looks back too far for the converter pilot.

I notched the back of the factory trans x member 1" x4" wide and it fit the th400 nice so now to make room for the mount/bushing.

The trans input shaft is about .200" away from the crank spacer so I will call PTC and let him know so I can get the .125" pilot in the spacer minimum needed.I need to cut the old trans fluid lines and re press the #6 fitting in and the temp sensor Tee in a good place and my Lokar dipstick looks like no problem clearing and rossler indexed the dipstick for the th400 and I am double triple measuring for the drive shaft to be made.I am glad things are moving along now.Any one have a question or input?

For what it's worth, I had a buddy with a '71 duster 20 years ago. When he got it...It had the top of the cross member cut out exactly like you've done to make yourT400 fit. Someone had chopped his out to put a 3 speed manual in the car, and the cross member was in the way of the shift rods if I remember right. This was a lowly mid 13 second car... nothing crazy.

Anyway... We converted it back to a 727 almost right after he bought it.

The odd thing was that it would break flex plates and trans mounts on a regular basis. After about 4 or 5 of them (even aftermarket SFI ones), we suspected maybe the missing frame cross member section had something to do with it.

My dad cut a piece of cross member out of a donor car and welded it back in for us. Never broke another flex plate again!!!!!

So just my 2 cents from my one and only experience.... with that crossmember piece missing it was a disaster.

Thank you I could always weld some angle in the cross member inside.I had to start somewhere.
