any info on the above like what would you have to do like new diff. brakes.stering ect

Well fatboy...... where to start. Most guys out there r probably saying oh der, becos if u know anything about early Holdens, this is practically the most common change made, and usually the first thing most owners do. Anyway, I'm asumming u just dont know so I'm gonna help u out. Ok, well the most common change over method for what u wanna do is this.....
You start by rippin out ur old motor (old greys are getting rare these days, so if uv got a good 1 & uv got room, keep it) and gear box as one unit. Drop ur front end out and replace it with a HR front end. They bolt straight in, the only real changes r in the brakes ul need to do ur homework here if ur changing to disks. Its not hard, but source ur parts well beforhand. While ur at it, its not hard to fit the HR column, that way doin it all at once. The column fits well and sits about an inch or 2 closer to the dash. As the HR ran red motors the engine mounts r in the right place for ur 202. use the old thermostat housing from the grey and u can use the original radiator. Alot of people use Torana diffs, & there r some other models too, but some may need to have the mounts cut off and the right ones welded on. If money is an option, u can change just the motor only. So u can keep everything else including the old 3 speed (yes it does bolt up, been there done that). You can keep the original kingpin front end, but keep in mind u'l need to weld on some engine mounts, as greys mounts r at the front not on the sides. U may also have to do ur home work about needing an engineers cert. as this is necc in some states, and sometimes in order to get one u may need to make the other mods I first mentioned. As the original 3 spd is a not syncro 1st(crunch box) some guys drop in a 3spd HQ box, this gives u synchro 1st and still gives u a column shift pattern.
Hope that helps u a little. Garry.

Just a couple of minor points on this.  You may not need an engineer's certificate for a 138 red or 149, but you will almost certainly need it for a 202.  In NSW that means: HR brakes, seat-belts, heater/demister, electric 2spd wipers (or single speed at > 45 sweep/min) must be fitted.
Garry's comments are fairly accurate, but I recomend you read the article on fitting a HR F/End on our website at http://www.fefcholden.org.au/techinfo/tech002.html ($2) as there are a couple of other tricks and traps.
hope that helps, RET

As below but keep in mind the engineer will test & check all mods & it won't  matter if you use HR or Torana F/Discs a preportioning valve will normall need to be installed to balance the brakes. I would use a HR rear as it is virtualy a bolt in job & with the HR front the track remains the same F & Back. Check your offset for any wheels you want to use as many stock 13in mags will scrub on guards, rolling them may avoid chewed tyres. I have 14s (HK-G) on mine which is another option. Depending on your prowess there are many kits available, Rod Hadfield is a good place to check.
