We don't have one in our Brochure link so if you wanted to take pictures of the pages and upload them that would be great
Brochures list options and trim levels so you can see what you have and don't have
Long bed(7ft) only came with regular cab, its rear axle is 6" farther back so different rear frame than regular cab or extended cab which both had the same 6ft beds
Long bed replacement beds are few and far between so keep yours rust free as much as possible
1989 was first year of generation 1.5, or some call it generation 2, lol
The mechanics were all the same from 1983 thru 1992, but the body style changed in 1989 thru 1992
In 1993 the body was made 2" wider but frame was same width, called generation 2.....or 3, lol
1998 had more changes with mechanics so was the 3rd or 4th gen, up thru 2011, last year
1989 2.9l had the newer head design, so less cracking issues than the 1986-1988 heads
The lifters are lubed thru cam bearings so as the engine got older they would make a "ticking" noise from lower oil pressure BUT..............it never caused engine damage so an annoyance not a sign of trouble
If its an automatic its an A4LD model, used from 1985 thru 2011, in 1995 it was renamed 4R55E, when more solenoids were added to valve body
In 2001 it was renamed again to the 5R55E, when 2 extra external sensor were added
But it was the same transmission internally as far as the rotating mass from 1985 thru 2011
If manual trans its a M5OD-R1(M5R1), good reliable transmission used from 1988 thru 2011
It does use ATF, yes automatic transmission fluid in a Manual transmission, holds 2.8quarts
So DO NOT put gear oil in it
