anybody know the nut size for the tran mount to the kmember, ordered a new mount and didn't come with the nuts, I let the old mount go with the AOD I took out. I guess I can always just take the mount with me to hardware store but if anyone had the info handy I'll take it.
Anyone have the bolt sizes for the A/C? If memory serves correct there are 4 that holds the compressor to thefront and rear brackets, then two that hold the rear bracket down to the aluminum piece that bolts to the head, then two that holds that aluminum piece to the head, and last is the long threaded rod that goes through everything. Into the block on one end and uses a nut on the other end. Want to run to Fastenal instead of buying a kit I don't need. Thanks!
I just replaced mine this summer all 6 are the same size they are 10mm x 1.5 x 24mm long.
