Floor Drain Hole Size??

Hey gettin ready to drill the 4xfloor drain holes into my new floor and would like to know the size I need to drill to be the same as original. Thanks Jesse

 

I can go out and measure the holes on my '69 later tonight. It still has the original floors. I'll put a reminder on my calendar.

 

You rock! Thanks man

 

Mine are roughly .990 1956 cj6
If you need locations let me know

 

Right on. Go figure theyd be 1 inch... the cover plate overlaps the the holes roughly 1/16 aroundIt? If you don’t mind taking a measurement, what would be the distance from front center hole to the front straight part of cowl support? As well as centre to center of the holes and uhhhh center hole to the inner side panel of Jeep maybe 13/4 or 2 inch??? Thanks Jesse

 

Looking For Floor Drain Measurements

Thanks so much for pics fyrmn very helpful and Dane for the link. I Would never of found that. I’ll post some pics thanks again

 

I seem to recall a 1 in hole saw fit well in the old holes.

• Have seen the floor drain covers at some different venders.Floor Drain Hole Cover, 50-52 Willys M38s - vintagejeepparts.com

Between the two holes is a welded nut for the thumb screw.

The origional thumb screws on my M38A1 were brass.

Thanks for the pic Dave. Pic will help me fab up those covers, have to find some rubber gasket material. I wouldnt use those odd rivets I’ll contact cement or something to the bottom of the covers. J

 

I don't understand those rivets, the originals which were in bad shape on the M38A1 did not have any rivets.

I think you've already have what you need, but I finally had time to measure mine. Holes are 1" diameter. Their centers are 7/8" forward and reaward from the center of the cover pivot hole. The cover pivot hole center is 3 1/2" back from the back of the cowl brace, and 1 3/4" inboard from the side wall.

 

Saw this and he has 10 available now:

Didn't think those small holes and rivets looked right.

I realized that I had my original floor and therefore drain hole on driver's side just recently. Had no idea they were there...Passenger side...Not so much. Nice, honest bubba'd patch job over there. Good to know that I have a source for replacement drain hole covers.

 

Thanks for all the info and measurments. Drains holes look good and fabbed up 14gauge covers and wing bolts.

 

The drain holes are i inch in diameter and are 1 and 3/4 inch apart. The little threaded piece is one inch long and oblong directly between the two holes.
The holes start 1.25 in in from the flange along the edge. I make those threaded pieces out of the same thickness metal and grind them to the proper shape.
