bell to engine, or bell to trans, some have side braces to trans.
3speed auto or 4 speed, ?
tough question, you lost ALL your bolts. (ouch) the are all metric.
the FSM nor the official Ecat, shows NO size.... (fact)
first off,.if not all lost then the other side there. are same size.
if the left is not missing , you have bolts to match to right.!
correct? take the left bolts to store and buy a match.
and the nuts. there.
there are 4 factors on these bolts. (suzuki still sells them)
1: diameter, most are 8 and 10 mm. measure the hole see that?
2: pitch, (iso spec sizes ) per above.
3: length (this too can be measured,)
4: grade. (id use grade 8.8) we dont have spec, so.... more is better.....
if not using OE parts.(suz)
you get to measure each hole first. (with a dial caliper)
measure inside diameter. or use 3 known bolts to find this out.
the MM diameter. 25.4 x inches = metric,
there are 2 big studs there too.
and finding that nut sizes is not hard. at all.
get diameter with caliper then buy the ISO pitch nut matching that.
there are fine and coarse ISO sizes. just looking answers that.
but if not, buy 2 nuts, that diameter in both fine and coarse.
bingo the nut is found.
as seen here
that same dial caliper tool (all shops have one..so.)
the rear measure depth. (basics)
the rear is insert in to a hole on trans to the block side and total depth is known (to rear edge of bell casing)
so buy mm length just less than that.
there is no easy way, only using a tool finds this out.
or use stick pushed in to hole an use thumb nail to mark stick
then measure that with any metric ruler. directly.
or just buy them. (they have no graphics for this level of detail back then so cant see them , must ask)
you will have to call them and tell them what's missing.
if you had listed all bolts missing i can give out real suz. part numbers. (i have a real hard copy parts list manual)
all this above is standard shop practices... how to measure bolts.
