4L65E fittings

Anyone know what fittings are used for a tight fit for my 4L65 swap into my 64? Ive seen where it can be a tight fit and a BFh has to make some room, would rather not have to do that.

64 Chevelle

The thread into the transmission is 1/4 inch STRAIGHT pipe. It has a sealing washer. Like this:

I guess I can come off of those with a couple 90s to some kind of flexible lines to keep it tight?

Re: 4L65E fittings

The top port is very close to the floor pan. I had AN6 fittings and lines ready to use, but they came out of the tran's too far, and no amount of "massaging" the floor pan would help. So I switched to stock lines for a 1999 Blazer.
PART# 624-100A and 624-101A ($15 each)
They snap in like stock, and hug the trans and the LS block. No problem with the headers.
I then cut and flared them right at the front of the motor and went with rubber line to the Trans cooler.
I cut a 2x2 square hole in the trans tunnel to get the top line to not hit the floor. But if the trans was out I could have probably dented up the floor to get it to fit.
