Finding correct length of engine oil dipstick on '91 S10
 

the dipstick on my 4x4 S10 broke in two while i had it pulled out. i went and got a universal that needs to be cut to correct length and now i cant seem to find one of the pieces of the original in order to measure.

any ideas on where to find the correct length? could somebody measure theirs and post up the length. i'd appreciate it!
