welcome to the group!!! anything part # wise that isn't on Jolly's original site, I can furnish. and i agree with ed, keep the sm420 and change the ring gear anf pinion. spicer/dana 44 series. 3.07 is the lowest gmc offered, however fmc had a 2.73 version as an option to the 9" chunk style and with the low 1st gear, it will still pull, while giving you highway speed. good luck, and junk them bowtie motors!!!!!!!!!!!
