64 Etc with 2004R dipstick and cooling lines compatibility

I am installing a 2004R into my 64 El Camino. Trying to accumulate the right parts ahead of time since have limited time on my friends rack.

1. Dipstick-Anyone sell a Factory type dipstick for the 200 that fits in the Chevelle?
**OPGI sells a 700r4 stick for a Chevelle retro fit but I don't know if that's appropriate for the 2004r either fit or indicator wise?

**Whether it be specific for a retro tranny fit to a Chevelle or just something that fits up ok, do you have a specific application I can buy?

I have used Lokar flex sticks on other apps and don't particularly like them.
Would like a Factory hard tube bolted to the bell housing like factory install.


2. Cooling lines-prefer to use hard lines. I have purchased from OPGI the lines for a 700r4 retro fit to a Chevelle. Hopefully I can adjust a little at the trans for the slightly different in/out location of the ports. Frame and radiator routing should be good I would think.
**Anyone experienced with this? Will they fit?

-I will make some hardline to couple up from rad to cooler and back to trans return line.

Thanks for the help
