Rear coil spring bolt sizes?

[kyull67]

Does anyone know the sizes of the upper and lower rear coil spring bolts? My old ones are too rusted and broken to tell. Thanks.

No one answered this yet?

I'll double check Friday but I think they are 3/8-16 x 1" for top and the same threads by about 4" for the bottom.

Expect an update 9-7-07 or send me a PM to remind me.

I just replaced mine, bottom is 1/2 x 5, top was 1/2 x 2. Make sure you get grade 8 bolts!!!!

I couldn't wait to install my new suspension, so I guessed and got pretty close. If I remember correctly; bottom coil spring bolts are 1/2" x 5" or 5 1/2", top coil spring bolts 1/2" x 2" or 2 1/2". The rear shock mount bolts are 1/2" x 2 1/2". I haven't got to the front shocks mount bolts yet, so if anyone know those sizes feel free to chime in.

Thanks. Mine are 400 miles away. They looked a little smaller from here
