Should i buy this 68 shortbed?

[337]

Former owner of a 68 shortbed.
Neighbor may his 68 shortbed for 1500.00

it is all factory:

straight 6 - 3 on the tree
no power anything / no a/c
body is decent
cab is better than good, less than excellent(no rust on quarters or floor or rocker panels)

If I buy, these are the goals:

350
disc front brakes
power brakes/power steering
A/C

My biggest problem will be the a/c - since factory trucks came with built in vents, and I've read the firewalls are different.

Should I keep looking for what i want - mainly a truck with a/c.

I live in Texas and will not survive in these metal ovens during slow summer day traffic.

sorry no pics
