Model T Ford Forum: Forum 2017: Rear Spring to Chassis U Bolts
Top of pagePrevious messageNext messageBottom of page Link to this message  By Alan George Long on Friday, December 08, 2017 - 02:23 am:

Just wondering how many different types of U Bolts are used
on the standard Model T passenger vehicle rear spring

Are there differences in the length (to cater for the later springs with extra leaves) and or width of the area that saddles the chassis?

Would a set of brackets from a 26/27 fit a early chassis? If not, it may not be possible to fit extra leaves is the standard tapered 8 leaf set up

Thanks for any feedback. Alan

Alan, there are different length U bolts. There are variations in the position of the split pin holes too. This will allow the fitting of different spring packs. I have no idea of the date of any changes. I just choose ones that fit the job in hand at the time.

Those rear spring clips are for the two different rear springs packs, 8-leaf and 9-leaf found on sedan and pickup.

The 8 leaf version Part#3388 (Fac. #T-326 or T-326A) would work for early taper leaf rear pack, it's approx. 3 1/2" long.

The 9 leaf spring clip is Part#3833B (Fac. # T-1737) and is 4" long, the cotter pin holes at approx. 3 5/8" to the end, that facilitates the extra leaf in the sedan rear spring

They changed the design of these in '26 too because of the strengthened rear cross member.
