Bolt plates to hold doors on are stripped!.. Now what?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

smoknbarrels · 05-07-2007, 07:25 PM

How can I fix completely stipped bolt holes in those un-removeable plates in my door pillars (holds the doors on)?? is it possible to get them out without doing too much dammage?
or should I just ream them out to a bigger size..?

anyone have luck with this?

Thanks.

Can you weld a nut on the inside of the door or is there not enough room to get in?

Maybe a JB WEld or Epoxy a nut on the back side?

smokn,there are several ways to repair those.You could maybe get away with reaming them but the larger bolts may cause interference.You could cut them out and replace(depends on your bodyworking skills).If you are looking for a fix that doesn't require welding you may be able to use a thread insert.You have to drill the hole and tap it then use a tool to screw an insert in.The bolt then threads into the insert.Heli-coil is probably the most well known.Someone else may have another solution or one that works better for you.The real long term fix is to cut them out and replace.One of these other methods may get you by on a driver or may be a temp fix until you do bodywork.At least this will get you a TTT

I don't know if you could reach the door plates but worth a try anyway. If this works you could get buy without re-welding which you may have to, to fix it right. Remove the door from the floor vent see if you can get to the plate that way. Might reach it, but not sure how it is secured. I cut a V slot in between the floor vent and replaced one then welded a thin plate over it. Turned out decent & not all that noticeable.

Try coarse thread bolts, factory is fine thread. I tried that on my orange and white and they seemed to thread fine into the stripped holes. They seem to still hold well. Or you could tap it for the coarse thread bolts to. That would be my first 2 suggestion to try.

id try this first before you got into something indepth

I haven't tried this, but what if you welded in the stripped hole (Not entirely but a few spots around the inside). Then retap the hole to the standard size and pitch as original.

I third this method. The fine threads can be cut for coarse threads with relative easy & plenty of strength.

you could turn the doors around and make suicide doors

, that is a fix i guess, but doesn't seem to be the direction i want to go at the moment..lol ,
so for the coarse thread bolt idea, I just simply turn a coarse thread bolt into the hole without even running a tap into it? will this actually hold the wight of the doors up?

I don't think a few spt welds in the hole would work either, wouldn't that make the steel too hard to tap and too un-even? I'd probabliy just end up breaking the tap off in the hole.

Aarons72s · 05-08-2007, 09:16 PM

I was able to just force the coarse theread bolts thru the stock holes without a tap, those plates are made of a soft steel. But if you got a tap or want to tap it then by all measns do it. Probably the better way to do it but the other way worked for me in a pinch.

WinDancer · 05-08-2007, 10:05 PM

Coarse threads are stronger than fine. Coat them with red threadlock and just run them on in slow and easy, so as not to heat them up and chance breaking one. When tight let sit for an hour or so, then you can get on with life again

Just be prepared for whoever takes them out having a horrid time. Practice up that 'I had no idea" face.
Good luck- let us know?

At least you still have something to thread. One of mine broke the captive nut off inside. I guess I'll have to cut the bolt to get the hinge off.

smoknbarrels · 05-09-2007, 12:55 PM

yea, the plate looks to have pretty soft metal, as 2/3'rds of the holes are stripped. I know if i try to just freash'n up the fine threads with the same size tap, I'm sure they'll just cross thread.
I'll give the coarse thread tap a go... should I go slightly oversize? or not nessasary?

Aarons72s · 05-09-2007, 02:19 PM

Same size bolt but coarse thread and you will be fine. That worked for me.

Those Inserts Are Called Helicoils. And They Are Sold At Any Parts Store Or Body Supply Shops. Or Check You Local Body Shop

I say go for the suicide doors.

or do the General Lee and weld the doors completly shut.
