Flash69 10 Report post Posted March 24, 2019 I am upgrading my radiator from a 20 inch to a 24 inch from eBay, based on a thread here. I purchased new repro upper and lower saddle brackets however I cannot find the bolts to mount the lower saddle bracket. I have searched many parts sites however I came up empty. Can anyone help me find bolts to use to mount the lower bracket? Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted March 24, 2019 I think they are sheet metal screws, not bolts. Quote Share this post Link to post Share on other sites
Flash69 10 Report post Posted March 24, 2019 The hole looked threaded however I was unable to look closely enough tonight. I will look tomorrow to see if they are treaded holes. Quote Share this post Link to post Share on other sites

I will look tomorrow to see if they are treaded holes. Just looked at the lower brackets and bolts I have in a bag for one of my 69s, I was wrong. They are 5/16 NC18 bolts with captive washers (like fender bolts). Total length (including the head) is 1 inch.They may be the same bolts that attach the front fender extensions to radiator support. The top support had 2 screws that attached the support to top of radiator support (besides the 2 bolts that go from front to radiator support). Don't know if the 2 screws that go from top are original or if someone added them. Quote Share this post Link to post Share on other sites
Ridge Runner 1,112 Report post Posted March 24, 2019 I believe they are called frame bolts ,they sort of have a taperd end where they thread in . They are the same thread as a fender bolt and if you are not worried about being original you can use a fender bolt 2 Caseyrhe and SWPruett reacted to this Quote Share this post Link to post Share on other sites

To the best of my knowledge the second set you reference are for the 20" radiator with side brackets to attached to the radiator core support. Quote Share this post Link to post Share on other sites
