first off you will need
drill press
drill vise
c-clamps
punch
first clamp your rear block into the vise
put a punch or anythang between the jaws (just to help get a good bite on block)
now lineup your rear block hole and drill
and clap the vise to the press table with your c-clamps
ok now slide your rec over the rear block
and bring the drill down (no pressure you just want to mark the rec)
now remove the rear block from vise and reinstall in rec
move the vise and drill your hole
lineup the second hole the same way you did the first
now mark and drill the second hole same as first only this time
after you slide the rec over the block install a long rivet threw the first hole you drilled to get placement perfect
to do the rivets heres the tool you will need
airhammer (moded bit)
hammer
and chunk of 2x2 plate with divet
place you backing plate (2x2x1/4 plate with divet) on somethang solid
now set the head of your rivet inside the divet and tap (vary lightly) on the rivet with a hammer
no big swings here just alot of little 1's
till you get your rivet head to swell to the correct size
now take your airhammer and round it out to form the rivet
its vary hard to take pics of the rivets with my pos cam
