: Bolt size for frt pass lower door hinge?

04-02-06, 09:47 AM
yo gang!
I did an extensive search here for the two Bolt sizes (prob both are same size) for front passenger lower door hinge (attaches hinge to door).

Did find this info w/pn's , diagrams, etc. [URL="http://www.pqparts.com/gmusa/cadillac_category_detailview.asp"] It is a 2001 Catera; http://www.pqparts.com/partscatalogs/cadillac/pictures/parts/OV10_015~3.jpg
I need the equivalent of Bolt #7 in diagram, View A, but for lower hinge - assuming it is same for lower hinge bolts. The bolt does not have a smooth shoulder area but is fully threaded

I tried a 7 x 1.0 30mm (all threads, not shank style) from homie depot but it is too large; top bolt is stripped, bottom bolt is missing, resulting in crunching when door is opened, swung, or closed.

I know I can go to smaller sizes and test, but car is on-the-move a lot and daughter works too much for me to get to it in a decent time of day or even a wave-by.

My last resort is fully supporting door and removing remaining bolt; going to NAPA, etc. and getting a match set, but as I mentioned, car is on trips and we're not close to her home.
TIA my friends!:thumbsup:
edited; corrected my bolt size error and added the bolt does not have a smooth shoulder area but is fully threaded

I have narrowed it down to a M5 x 18
I'll try another Caddie dealer parts person monday; dealership where she bought it from won't help at all; too busy to look it up.
prob. tap stripped hinge hole w/SAE .228 and use the SAE bolt.

Sorry for the misunderstanding, miesk5.

I sought out, located, and posted the below TSB with the hope it would assist you. But afterward I realized my post was NOT germane and would NOT help you. I tried to withdraw what I had done mistakenly, but was unable to discover a way to cancel my post and remove my error completely. Instead it ended up looking as it does now.

Hope you can forgive - I meant no harm or offense and I regret my inability to assist. I wish you good luck and success with your project.:)

btw, we are getting NO help at all from 4 Cad dealers here; next on the list are dealerships over 50 miles away, but that is iffy since they say by phone, that they can not locate the kit cited in the TSB that consists of 2 brackets and 1 support. Yards don't want to pull out the items; will only sell complete door.
Weill try local body shops next; they can probmake the support,but the bracket may need a Macgyver solution.
