has anyone used this site before? http://www.americanshifter.com/products/Custom-Laser-Engraved-Shift-Knobs/

i was wondering if the thread size on these (16mm x 1.5) will fit the nv5600 stick in my 2001 dodge? cant find any info on the search feature about the thread size on the stick

I have a Geno's shift knob and it says M10 x 1.5mm. Works for '89-'12 trucks. Tried the link and it didn't work for me. I found these adapters from the same company. I have not used them personally, but at least it will let you use the shift knob. http://www.summitracing.com/parts/hfm-00423/applications/?prefilter=1

so that pack of adapters in the link will let me use the shift knob?

From everything I read - Yes they should work. I see they are made by same manufacturer as your shift knob. Wouldn't hurt to call and confirm with them. Edit: I tried the link again and it worked. There is a link on the page to the chart of adapters, its looks like ASCAD14 is the one you want. I just did a search and came up with the assortment in my previous post.

thank you i sure appreciate it!!
